1 00:00:00,720 --> 00:00:04,040 Speaker 1: December first was World Aid's Day, and December the entire 2 00:00:04,080 --> 00:00:06,880 Speaker 1: month is HIV Awareness Month. 3 00:00:06,760 --> 00:00:10,040 Speaker 2: And this December is particularly important because it's the fortieth 4 00:00:10,039 --> 00:00:13,760 Speaker 2: anniversary of the first five cases of HIV. 5 00:00:14,120 --> 00:00:17,640 Speaker 1: Wow, forty years feels like not a long time, but 6 00:00:17,800 --> 00:00:20,079 Speaker 1: so much has happened in those forty years. 7 00:00:20,079 --> 00:00:23,279 Speaker 2: It's definitely not a long scientific time, you know, And 8 00:00:23,360 --> 00:00:26,360 Speaker 2: you're right, so much has happened. Even thinking about what 9 00:00:26,440 --> 00:00:29,880 Speaker 2: it meant to have HIV in the eighties and what 10 00:00:29,920 --> 00:00:32,280 Speaker 2: it meant for your life compared to what it means 11 00:00:32,280 --> 00:00:35,879 Speaker 2: now thanks to advances in medicine and vaxine development, all 12 00:00:35,960 --> 00:00:38,040 Speaker 2: kinds of things that are coming along for the treatment 13 00:00:38,040 --> 00:00:39,360 Speaker 2: of HIV and AIDS. 14 00:00:39,200 --> 00:00:43,240 Speaker 1: Right, and our understanding I think of the virus has changed, yes, 15 00:00:43,440 --> 00:00:46,280 Speaker 1: and the way that we interact with people who have 16 00:00:46,520 --> 00:00:48,440 Speaker 1: HIV has changed, thankfully. 17 00:00:48,640 --> 00:00:51,400 Speaker 2: You're right. I think there's so much to unpack even 18 00:00:51,400 --> 00:00:55,960 Speaker 2: though it's a short scientific time. There have been incredible developments, absolutely, 19 00:00:56,000 --> 00:01:08,319 Speaker 2: and I can't wait for us to learn all about it. 20 00:01:23,240 --> 00:01:27,080 Speaker 1: Welcome to Dope Labs, a weekly podcast that mixes hardcore science, 21 00:01:27,240 --> 00:01:29,319 Speaker 1: pop culture, and a healthy dose of friendship. 22 00:01:29,520 --> 00:01:32,920 Speaker 2: This week, we're talking all about HIV Now, HIV has 23 00:01:32,920 --> 00:01:35,080 Speaker 2: been around for a while, and there's been all kinds 24 00:01:35,080 --> 00:01:37,039 Speaker 2: of rumors like, oh, they have a cure and the 25 00:01:37,080 --> 00:01:39,399 Speaker 2: government just doesn't want us to have it. But scientists 26 00:01:39,440 --> 00:01:41,720 Speaker 2: have been working on an HIV vaccine for a pretty 27 00:01:41,760 --> 00:01:44,640 Speaker 2: long time. Yeah, there's a lot swirling around, But what's 28 00:01:44,760 --> 00:01:47,319 Speaker 2: most important is what the science is telling us, and 29 00:01:47,400 --> 00:01:49,200 Speaker 2: that's what we're going to get into today. I just 30 00:01:49,240 --> 00:01:52,160 Speaker 2: saw this story in the Washington Post about an Argentinian 31 00:01:52,200 --> 00:01:56,080 Speaker 2: woman who just became the second person on record whose 32 00:01:56,120 --> 00:02:00,240 Speaker 2: body might have completely eliminated the HIV virus on its own. 33 00:02:00,440 --> 00:02:02,800 Speaker 2: And when something like this happens, it's a huge deal 34 00:02:02,880 --> 00:02:05,880 Speaker 2: for scientists who can study what happened in the patient's 35 00:02:05,920 --> 00:02:09,040 Speaker 2: body and potentially use those findings to develop a cure. 36 00:02:09,440 --> 00:02:13,639 Speaker 2: Let's get into the recitation. 37 00:02:21,520 --> 00:02:22,320 Speaker 1: So what do we know. 38 00:02:22,639 --> 00:02:25,400 Speaker 2: Well, we know HIV stands for the human immuno deficiency 39 00:02:25,520 --> 00:02:28,200 Speaker 2: virus and it's been around for a long time. It's 40 00:02:28,240 --> 00:02:30,560 Speaker 2: been about forty years since the first case of HIV 41 00:02:30,720 --> 00:02:31,400 Speaker 2: was diagnosed. 42 00:02:31,639 --> 00:02:34,919 Speaker 1: We also know that HIV is the virus that causes AIDS, 43 00:02:34,960 --> 00:02:37,640 Speaker 1: so that's similar to how SARS CoV two is the 44 00:02:37,720 --> 00:02:40,800 Speaker 1: virus that can lead to COVID nineteen and HIV affects 45 00:02:40,800 --> 00:02:41,440 Speaker 1: a lot of people. 46 00:02:41,520 --> 00:02:44,680 Speaker 2: So about thirty seven million people worldwide have HIV, and 47 00:02:45,040 --> 00:02:47,279 Speaker 2: about one point two million of those are Americans. 48 00:02:47,480 --> 00:02:50,040 Speaker 1: And we know that HIV is a virus that attacks 49 00:02:50,040 --> 00:02:52,600 Speaker 1: the body's immune system and if it goes untreated, it 50 00:02:52,600 --> 00:02:55,919 Speaker 1: can lead to AIDS. So currently there's no cure for HIV, 51 00:02:56,040 --> 00:02:58,520 Speaker 1: but there are ways to control it through treatment that 52 00:02:58,600 --> 00:03:01,960 Speaker 1: allow those living with HIV to have long, healthy lives. 53 00:03:02,240 --> 00:03:04,000 Speaker 1: So what do we want to know? I think I 54 00:03:04,040 --> 00:03:08,200 Speaker 1: want to know how is the vaccine development for HIV 55 00:03:08,560 --> 00:03:11,280 Speaker 1: different from other types of vaccine development. We've talked about 56 00:03:11,320 --> 00:03:15,119 Speaker 1: vaccine development in previous labs, and so I'm curious if 57 00:03:15,120 --> 00:03:18,160 Speaker 1: it's the same, it's different, and if it's different, how 58 00:03:18,240 --> 00:03:18,760 Speaker 1: is it different? 59 00:03:18,840 --> 00:03:21,480 Speaker 2: And I think before we can even get to vaccine development, 60 00:03:21,760 --> 00:03:25,519 Speaker 2: I need to know some basic biology about HIV. What's 61 00:03:25,520 --> 00:03:26,959 Speaker 2: it looking like, how's it working? 62 00:03:27,160 --> 00:03:27,320 Speaker 3: You know? 63 00:03:27,320 --> 00:03:28,720 Speaker 2: I think we have to kind of understand those things 64 00:03:28,760 --> 00:03:30,120 Speaker 2: before we know how we're going to stop it in 65 00:03:30,160 --> 00:03:32,200 Speaker 2: its tracks. I also want to know the timeline to 66 00:03:32,240 --> 00:03:34,519 Speaker 2: getting here. We didn't just start trying to make a 67 00:03:34,600 --> 00:03:38,560 Speaker 2: vaccine first. There were medicines made available that now feel 68 00:03:38,600 --> 00:03:41,080 Speaker 2: like super medicines compared to what may have seemed possible 69 00:03:41,120 --> 00:03:43,400 Speaker 2: in the eighties. So there are things that can make 70 00:03:43,600 --> 00:03:47,520 Speaker 2: HIV undetectable and thus non transmissible. And why is this 71 00:03:47,600 --> 00:03:51,560 Speaker 2: virus so different from other viruses that it's taken so 72 00:03:51,920 --> 00:03:54,520 Speaker 2: long to develop a vaccine? COVID got us one in 73 00:03:54,560 --> 00:03:58,200 Speaker 2: the vaccine in two years every time, yet hyper speed. 74 00:03:58,320 --> 00:04:01,480 Speaker 2: But this is a very good question. Let's jump into 75 00:04:01,480 --> 00:04:10,360 Speaker 2: the dissection. Our guest for the next two laps is 76 00:04:10,360 --> 00:04:11,680 Speaker 2: doctor Christine Daniels. 77 00:04:11,720 --> 00:04:14,000 Speaker 4: My name is Christine Daniels, and I recently finished my 78 00:04:14,040 --> 00:04:17,480 Speaker 4: post doc at Duke University's Human Vaccine Institute. Christine's work 79 00:04:17,520 --> 00:04:22,039 Speaker 4: focuses on developing and testing novel or new vaccine candidates. 80 00:04:22,320 --> 00:04:25,680 Speaker 1: Christine is another one of me and Zakia's actual friends 81 00:04:25,680 --> 00:04:27,960 Speaker 1: in real life. We always tell you we know some 82 00:04:28,160 --> 00:04:30,479 Speaker 1: very smart people. We all went to Douke at the 83 00:04:30,560 --> 00:04:34,120 Speaker 1: same time, and so you might hear us call her Christine, 84 00:04:34,360 --> 00:04:41,159 Speaker 1: but it is definitely doctor Daniels. Okay, so first things first, 85 00:04:41,240 --> 00:04:45,280 Speaker 1: let's talk about the HIV virus and to understand what 86 00:04:45,320 --> 00:04:47,360 Speaker 1: it is and how it works. We ask doctor Daniels 87 00:04:47,400 --> 00:04:50,080 Speaker 1: to explain it to us in the context of sarskov two, 88 00:04:50,279 --> 00:04:51,960 Speaker 1: the virus that causes COVID nineteen. 89 00:04:52,200 --> 00:04:55,960 Speaker 4: So broadly speaking, HIV and sarskobe two are very similar. 90 00:04:56,040 --> 00:04:58,760 Speaker 2: Let's start with their structure. HIV and sars kov two 91 00:04:58,880 --> 00:05:00,000 Speaker 2: have a pretty similar structure. 92 00:05:00,160 --> 00:05:01,640 Speaker 3: They're both envelope viruses. 93 00:05:01,839 --> 00:05:04,880 Speaker 1: This means that the virus is surrounded by an outer shell. 94 00:05:05,120 --> 00:05:06,360 Speaker 3: They're both expressed. 95 00:05:06,400 --> 00:05:11,440 Speaker 4: Their glycoproteins, or their spike proteins per se on their surface. 96 00:05:11,160 --> 00:05:13,560 Speaker 2: So that envelope or outer shell of the virus is 97 00:05:13,560 --> 00:05:17,000 Speaker 2: covered in these little spikes or proteins, and those proteins 98 00:05:17,040 --> 00:05:19,800 Speaker 2: have little sugars that's the glyco attached to them, and 99 00:05:19,880 --> 00:05:23,560 Speaker 2: those proteins allow the virus to bind or dock onto 100 00:05:23,600 --> 00:05:25,760 Speaker 2: host cells and that leads to infection. 101 00:05:26,000 --> 00:05:29,760 Speaker 1: And HIV and sarscov two are also similar in terms 102 00:05:29,839 --> 00:05:31,120 Speaker 1: of their genetic material. 103 00:05:31,279 --> 00:05:32,680 Speaker 3: They're both RNA viruses. 104 00:05:32,880 --> 00:05:36,240 Speaker 2: This means that they have single stranded RNA or ribonucleic 105 00:05:36,279 --> 00:05:39,520 Speaker 2: acid as their genetic material instead of double stranded DNA 106 00:05:39,640 --> 00:05:40,479 Speaker 2: like human cells have. 107 00:05:40,880 --> 00:05:45,839 Speaker 1: So in each HIV particle, you've got RNA inside surrounded 108 00:05:45,880 --> 00:05:50,039 Speaker 1: by the envelope with a bunch of little spikes all over. 109 00:05:50,320 --> 00:05:54,240 Speaker 1: Called glycoproteins, and so when HIV enters the bloodstream and 110 00:05:54,320 --> 00:05:56,800 Speaker 1: makes contact with the sell those little spikes are attaching 111 00:05:56,839 --> 00:05:59,159 Speaker 1: to the surface and they begin to fuse with the 112 00:05:59,160 --> 00:06:02,200 Speaker 1: host cell. This allows the center of the HIV particle, 113 00:06:02,200 --> 00:06:04,640 Speaker 1: that RNA, to go right into the whole sale and 114 00:06:04,720 --> 00:06:08,560 Speaker 1: to get converted back into DNA. So now you've got 115 00:06:08,640 --> 00:06:12,160 Speaker 1: viral DNA in your wholesale. So from there, the wholesale 116 00:06:12,240 --> 00:06:15,360 Speaker 1: is hijacked by HIV and begins to make more HIV 117 00:06:15,440 --> 00:06:19,040 Speaker 1: particles inside the body. But our body has an amazing 118 00:06:19,360 --> 00:06:22,359 Speaker 1: natural defense when it comes to fighting off viruses, the 119 00:06:22,400 --> 00:06:25,720 Speaker 1: immune system, and when our immune system senses that there 120 00:06:25,800 --> 00:06:29,120 Speaker 1: is an intruder, it can unleash a swarm of targeted 121 00:06:29,320 --> 00:06:33,360 Speaker 1: and general antibodies that will attack the virus, neutralizing it. 122 00:06:33,520 --> 00:06:35,920 Speaker 2: So remember those spikes we talked about covering the outside 123 00:06:35,960 --> 00:06:40,240 Speaker 2: of the virus. Those glycoproteins are what's specifically targeted by antibodies. 124 00:06:40,440 --> 00:06:45,440 Speaker 2: So stars CoV two and HIV viruses are structurally so similar. 125 00:06:45,600 --> 00:06:48,240 Speaker 2: In fact, the decades that have gone into developing the 126 00:06:48,400 --> 00:06:52,000 Speaker 2: HIV vaccine made it possible to develop the COVID vaccine 127 00:06:52,040 --> 00:06:53,000 Speaker 2: so quickly. 128 00:06:52,960 --> 00:06:56,440 Speaker 4: Because they're so structurally similar, we're able to leverage the 129 00:06:56,480 --> 00:06:59,320 Speaker 4: structure based a vaccine platform to design a vaccine for 130 00:06:59,360 --> 00:07:00,000 Speaker 4: COVID nineteen. 131 00:07:00,120 --> 00:07:03,320 Speaker 2: So understanding what the virus looks like structurally, what happens 132 00:07:03,320 --> 00:07:06,600 Speaker 2: when it gets into your body? How are vaccines disrupting 133 00:07:06,640 --> 00:07:09,159 Speaker 2: this process? How do they work? Doctor Daniels gave us 134 00:07:09,160 --> 00:07:12,640 Speaker 2: a great analogy. She thinks of a vaccine like a mugshot. 135 00:07:12,720 --> 00:07:14,840 Speaker 2: The vaccine is going to tell your body, Hey, this 136 00:07:14,880 --> 00:07:16,960 Speaker 2: is who you're looking for. This particle looks like this, 137 00:07:17,120 --> 00:07:19,600 Speaker 2: It has this certain protein on it. When you see it, 138 00:07:19,720 --> 00:07:30,800 Speaker 2: you know what to do. All systems go. 139 00:07:34,120 --> 00:07:37,240 Speaker 1: Now that we know generally how the HIV particle is 140 00:07:37,320 --> 00:07:41,480 Speaker 1: structured and how vaccines work in general, how would an 141 00:07:41,520 --> 00:07:43,840 Speaker 1: effective HIV vaccine work. 142 00:07:44,080 --> 00:07:47,360 Speaker 4: My lab specialized in protein design and expression, so we 143 00:07:47,480 --> 00:07:49,960 Speaker 4: use what we know about how the natural virus is 144 00:07:50,000 --> 00:07:52,520 Speaker 4: structured in its modes of infections in order to design 145 00:07:52,560 --> 00:07:56,160 Speaker 4: synthetic versions of it that mimic the virus but aren't infectious. 146 00:07:56,320 --> 00:07:58,480 Speaker 4: And using what we know, we're able to modify these 147 00:07:58,480 --> 00:08:01,600 Speaker 4: synthetic versions of the virus to help increase the body's 148 00:08:01,680 --> 00:08:05,400 Speaker 4: chances of recognizing them. Basically, instead of trying to redesign 149 00:08:05,400 --> 00:08:07,760 Speaker 4: a fake version of the entire virus. You just take 150 00:08:07,800 --> 00:08:09,880 Speaker 4: the piece of the virus that your body sees and 151 00:08:09,920 --> 00:08:12,120 Speaker 4: develops an immune response against, and that piece of the 152 00:08:12,280 --> 00:08:15,040 Speaker 4: HIV virus that your body sees, that's those spike proteins 153 00:08:15,040 --> 00:08:17,080 Speaker 4: we talked about that are spread out all over the 154 00:08:17,160 --> 00:08:19,880 Speaker 4: envelope of the virus, the glycoproteins. So you have this 155 00:08:19,920 --> 00:08:22,560 Speaker 4: big virus and you have these proteins spiking all over 156 00:08:22,560 --> 00:08:24,920 Speaker 4: the surface. We just take one of those spike proteins 157 00:08:24,920 --> 00:08:26,280 Speaker 4: and we just want to show that to the body 158 00:08:26,360 --> 00:08:30,040 Speaker 4: so the body focuses on the right region. The problem is, though, 159 00:08:30,120 --> 00:08:32,880 Speaker 4: that sometimes just one little piece isn't enough for the 160 00:08:32,880 --> 00:08:35,959 Speaker 4: body to generate a strong immune response. And so what 161 00:08:36,000 --> 00:08:38,040 Speaker 4: you can do is you can attach that piece, so 162 00:08:38,120 --> 00:08:41,520 Speaker 4: that spike that envelope protein onto a nanoparticle and you 163 00:08:41,520 --> 00:08:43,920 Speaker 4: can display multiple copies, so it's kind of like a 164 00:08:43,920 --> 00:08:46,760 Speaker 4: mini virus. And also the NATO particle itself is composed 165 00:08:46,800 --> 00:08:49,679 Speaker 4: of materials that will also activate your immune response. So 166 00:08:49,720 --> 00:08:52,000 Speaker 4: you get a robust immune response because you're showing multiple 167 00:08:52,000 --> 00:08:54,760 Speaker 4: copies of the right target. And then you have something 168 00:08:54,840 --> 00:08:58,439 Speaker 4: else that's stimulating supporting cells to help enhance that immune response. 169 00:08:58,679 --> 00:09:01,000 Speaker 1: All of this is blowing my mind. So doctor Daniels 170 00:09:01,000 --> 00:09:03,439 Speaker 1: works on creating a copy of the envelope of an 171 00:09:03,559 --> 00:09:07,560 Speaker 1: HIV particle covered in those glycoprotein spikes that your body 172 00:09:07,559 --> 00:09:10,480 Speaker 1: will recognize and develop a defense against. And by the way, 173 00:09:10,600 --> 00:09:14,600 Speaker 1: sorry's CoV two vaccines. You know, Maderna, Pfizer, and Johnson 174 00:09:14,600 --> 00:09:18,360 Speaker 1: and Johnson. They may have different strategies, but they all 175 00:09:18,440 --> 00:09:21,320 Speaker 1: are working towards the same goal to help your body 176 00:09:21,320 --> 00:09:25,440 Speaker 1: create a strong immune response against the coronavirus spike protein 177 00:09:25,600 --> 00:09:27,600 Speaker 1: that surrounds the virus. 178 00:09:27,360 --> 00:09:30,840 Speaker 2: And antibodies are one part of that immune response. Antibodies 179 00:09:30,880 --> 00:09:34,120 Speaker 2: are tiny proteins that help your body recognize and clear 180 00:09:34,320 --> 00:09:37,920 Speaker 2: foreign toxins, bacteria, and viral particles. 181 00:09:38,080 --> 00:09:39,800 Speaker 1: So they're like the bouncers outside the club. 182 00:09:40,160 --> 00:09:45,040 Speaker 2: Yes, that's perfect, And Christine mentions neutralizing antibodies And if 183 00:09:45,080 --> 00:09:49,000 Speaker 2: you play on that bouncer metaphor, neutralizing antibodies are binding 184 00:09:49,040 --> 00:09:51,760 Speaker 2: to the outside of a viral particle, so that those 185 00:09:51,800 --> 00:09:54,199 Speaker 2: spike proteins can't bind to any whost sales. So it's 186 00:09:54,280 --> 00:09:56,880 Speaker 2: like if the bouncers make a circle around you, right, 187 00:09:57,480 --> 00:10:00,600 Speaker 2: don't have contact, You're not what I see like when 188 00:10:00,600 --> 00:10:02,319 Speaker 2: they pick you up, when they hold the arms and 189 00:10:02,360 --> 00:10:04,520 Speaker 2: the legs and carry you out the club. That's what 190 00:10:04,559 --> 00:10:06,000 Speaker 2: neutralizing antibodies are doing. 191 00:10:06,040 --> 00:10:08,600 Speaker 1: I've seen that happen to some people. It's pretty embarrassing. 192 00:10:08,720 --> 00:10:12,360 Speaker 1: They say, your evening is over, it's time to retire 193 00:10:12,440 --> 00:10:13,160 Speaker 1: to the boudoir. 194 00:10:15,520 --> 00:10:18,040 Speaker 2: This is really amazing work. Tt It feels like something 195 00:10:18,200 --> 00:10:21,040 Speaker 2: we would do if we had a lab together. Yeah, 196 00:10:21,160 --> 00:10:23,199 Speaker 2: biology with nanoparticles. 197 00:10:23,320 --> 00:10:24,760 Speaker 1: Oh yeah, we'd be all over it. 198 00:10:24,800 --> 00:10:26,760 Speaker 2: Man, this must be really challenging work though. 199 00:10:27,360 --> 00:10:29,040 Speaker 1: Yes, I don't want to pretend like I know how 200 00:10:29,040 --> 00:10:32,840 Speaker 1: to do everything with nanoparticles same, but it sounds so cool. 201 00:10:33,120 --> 00:10:33,880 Speaker 1: I would love this. 202 00:10:34,120 --> 00:10:35,760 Speaker 2: All right, we're going to take a break, but when 203 00:10:35,800 --> 00:10:37,440 Speaker 2: we get back, we're going to talk to doctor Daniels 204 00:10:37,440 --> 00:10:39,920 Speaker 2: about the progress we've made so far towards an effective 205 00:10:40,040 --> 00:10:42,400 Speaker 2: HIV vaccine and how far we have to go. 206 00:11:01,480 --> 00:11:03,600 Speaker 1: We're back and right before we want to break, we 207 00:11:03,679 --> 00:11:08,559 Speaker 1: talked about non neutralizing antibodies, neutralizing antibodies and everything in between. 208 00:11:08,800 --> 00:11:11,200 Speaker 1: But if you want to know more about that, make 209 00:11:11,240 --> 00:11:13,719 Speaker 1: sure that you tune into our episodes in the New Year, 210 00:11:13,720 --> 00:11:17,200 Speaker 1: where we're talking all about the immune system. And before 211 00:11:17,240 --> 00:11:20,120 Speaker 1: we get back to talking about the HIV vaccine Zakia. 212 00:11:20,200 --> 00:11:21,520 Speaker 1: What's on tap next week. 213 00:11:21,800 --> 00:11:24,720 Speaker 2: Next week, we're continuing our conversation with doctor Daniels around 214 00:11:24,720 --> 00:11:27,880 Speaker 2: the development of an effective HIV vaccine, But we're gonna 215 00:11:27,880 --> 00:11:30,240 Speaker 2: shift the lens just a little bit from the science 216 00:11:30,360 --> 00:11:33,040 Speaker 2: to the people, because we know science doesn't happen in 217 00:11:33,080 --> 00:11:35,720 Speaker 2: a vacuum. So we'll be talking through the social context 218 00:11:35,720 --> 00:11:38,920 Speaker 2: around HIV over the past forty years and the people 219 00:11:38,920 --> 00:11:40,079 Speaker 2: who are affected most. 220 00:11:40,480 --> 00:11:41,920 Speaker 1: All right, let's get back to the show. 221 00:11:43,920 --> 00:11:46,719 Speaker 2: So here's what I want to know. We understand the similarities, 222 00:11:47,040 --> 00:11:49,880 Speaker 2: and we understand that work on the HIV vaccine could 223 00:11:49,920 --> 00:11:53,520 Speaker 2: have provided some scaffolding for process and distribution and other 224 00:11:53,559 --> 00:11:56,360 Speaker 2: developments with the COVID nineteen vaccine. But the COVID nineteen 225 00:11:56,440 --> 00:11:58,760 Speaker 2: vaccine got up and running pretty quickly, and we know, 226 00:11:59,120 --> 00:12:00,760 Speaker 2: you know a lot of people we're working on it. 227 00:12:00,800 --> 00:12:01,240 Speaker 2: A lot of. 228 00:12:01,200 --> 00:12:02,440 Speaker 1: Resources were poured into it. 229 00:12:02,920 --> 00:12:05,640 Speaker 2: What's been taking the HIV vaccine, which has been a 230 00:12:05,640 --> 00:12:08,320 Speaker 2: development for many decades, what's been taking it so long? 231 00:12:08,440 --> 00:12:11,319 Speaker 2: So COVID was developed really quickly because it's an easier 232 00:12:11,360 --> 00:12:13,439 Speaker 2: pathogen to design a vaccine against. 233 00:12:13,480 --> 00:12:17,640 Speaker 1: So even though HIV and SARS CoV two are structurally 234 00:12:17,760 --> 00:12:21,559 Speaker 1: similar and are both RNA viruses that use RNA as 235 00:12:21,600 --> 00:12:25,280 Speaker 1: their primary genetic material. A major difference is that SARS 236 00:12:25,280 --> 00:12:28,440 Speaker 1: CoV two doesn't mutate as frequently as HIV. 237 00:12:29,040 --> 00:12:33,280 Speaker 4: HIV mutates incredibly quickly. It can incur about ten mutations 238 00:12:33,320 --> 00:12:36,400 Speaker 4: per replication cycle, and the replication cycle is less than 239 00:12:36,440 --> 00:12:39,320 Speaker 4: twenty four hours. Scientists have estimate that one mutation of 240 00:12:39,360 --> 00:12:42,680 Speaker 4: SARS CoV two is established every eleven days or so. 241 00:12:42,679 --> 00:12:46,280 Speaker 4: So now we're looking at HIV having a mutation rate 242 00:12:46,320 --> 00:12:49,680 Speaker 4: this four times that of sars CoV two. So developing 243 00:12:49,679 --> 00:12:52,760 Speaker 4: a vaccine is able to accommodate all of that variation, 244 00:12:52,840 --> 00:12:55,600 Speaker 4: it's just really hard to do. So the way that 245 00:12:55,640 --> 00:12:58,440 Speaker 4: we try to do that is by designing vaccines that 246 00:12:58,480 --> 00:13:01,679 Speaker 4: are based on the conserved or of the HIV virus, 247 00:13:01,840 --> 00:13:04,240 Speaker 4: and so even if the virus mutates, those are regions 248 00:13:04,280 --> 00:13:07,600 Speaker 4: that don't mutate as frequently, and so if you get 249 00:13:07,640 --> 00:13:10,000 Speaker 4: a response against those sites, then you can likely be 250 00:13:10,040 --> 00:13:13,600 Speaker 4: protected against a wide range of viruses. So that's the approach, 251 00:13:13,600 --> 00:13:15,600 Speaker 4: and that theoretically you know that should work. 252 00:13:15,760 --> 00:13:19,200 Speaker 1: The other challenge for developing an HIV vaccine is the 253 00:13:19,320 --> 00:13:23,160 Speaker 1: length of time of infection. The infection window for sarskov 254 00:13:23,280 --> 00:13:27,000 Speaker 1: two is much shorter than HIV, and like we said before, 255 00:13:27,240 --> 00:13:31,240 Speaker 1: once someone is infected, that person has HIV for life 256 00:13:31,320 --> 00:13:32,880 Speaker 1: with very few exceptions. 257 00:13:32,960 --> 00:13:36,520 Speaker 4: So an HIV infected individual can live with HIV and 258 00:13:36,559 --> 00:13:38,880 Speaker 4: not experience any symptoms for a long time even though 259 00:13:38,880 --> 00:13:41,760 Speaker 4: they're infected with virus and it's infecting a body, and 260 00:13:41,800 --> 00:13:43,480 Speaker 4: not display symptom until they're very sick. 261 00:13:43,559 --> 00:13:46,480 Speaker 2: That also means there's a much longer window for HIV 262 00:13:46,640 --> 00:13:48,480 Speaker 2: to replicate inside your body, so. 263 00:13:48,440 --> 00:13:51,320 Speaker 4: It can mutate, but it's less probable just based on 264 00:13:51,360 --> 00:13:53,280 Speaker 4: that time window and the amount of times that would 265 00:13:53,320 --> 00:13:55,720 Speaker 4: have to replicate in a person within that time window. 266 00:13:56,000 --> 00:13:59,959 Speaker 1: And lastly, HIV is particularly elusive because it's able to 267 00:14:00,280 --> 00:14:03,600 Speaker 1: essentially hide itself from the immune system until it's too late. 268 00:14:04,080 --> 00:14:08,080 Speaker 1: HIV is covered with these sugars called glycans. The glycans 269 00:14:08,080 --> 00:14:11,240 Speaker 1: can attach to the envelope, that hard candy shell of 270 00:14:11,320 --> 00:14:14,840 Speaker 1: the virus and effectively hide the spike proteins from any 271 00:14:14,920 --> 00:14:17,679 Speaker 1: suspecting antibodies. So that's the challenge. 272 00:14:17,760 --> 00:14:19,960 Speaker 4: How do you generate a response that is able to 273 00:14:20,080 --> 00:14:22,880 Speaker 4: learn to bind or obade those black cans to target 274 00:14:22,920 --> 00:14:23,280 Speaker 4: the site. 275 00:14:23,440 --> 00:14:25,600 Speaker 2: That's really tricky because cells in our body naturally have 276 00:14:25,680 --> 00:14:28,840 Speaker 2: glycans all over them, So your immune system isn't going 277 00:14:28,960 --> 00:14:31,160 Speaker 2: to kick in the gear when it sees glycans because 278 00:14:31,200 --> 00:14:33,600 Speaker 2: that would mean you're essentially attacking yourself. 279 00:14:33,880 --> 00:14:37,240 Speaker 4: So in order to generate an effective HIV vaccine, we 280 00:14:37,280 --> 00:14:39,800 Speaker 4: need to figure out a way to generate antibodies that 281 00:14:39,880 --> 00:14:42,520 Speaker 4: are able to bind to the glycans and to the 282 00:14:42,560 --> 00:14:45,560 Speaker 4: protein at the same times. That way they won't be autoreactive. 283 00:14:45,680 --> 00:14:46,680 Speaker 4: And that's just hard to do. 284 00:14:46,840 --> 00:14:50,360 Speaker 2: I have a new appreciation for the challenges associated with 285 00:14:50,440 --> 00:14:52,120 Speaker 2: vaccine design against HIV. 286 00:14:52,400 --> 00:14:55,360 Speaker 1: Right, imagine trying to do a puzzle and every time 287 00:14:55,520 --> 00:14:57,520 Speaker 1: you go to put a piece down, all the pieces 288 00:14:57,680 --> 00:14:59,000 Speaker 1: change their shape. 289 00:14:58,800 --> 00:15:00,720 Speaker 2: Or they're saying you basic, we got to put down 290 00:15:00,760 --> 00:15:02,640 Speaker 2: two pieces at a time glancing in protein. 291 00:15:02,840 --> 00:15:06,240 Speaker 1: Yeah, it's no wonder this vaccine is so hard to develop. 292 00:15:06,360 --> 00:15:10,440 Speaker 2: But you know, vaccines aren't the only line of defense. PREP, 293 00:15:10,640 --> 00:15:14,000 Speaker 2: which is pre exposure prophylaxis, is medicine that people can 294 00:15:14,040 --> 00:15:17,520 Speaker 2: take to prevent getting HIV. So when you take PREP 295 00:15:17,560 --> 00:15:21,000 Speaker 2: as prescribed, it will reduce your risk of contracting HIV 296 00:15:21,120 --> 00:15:24,800 Speaker 2: from sex by about ninety nine percent. That's a huge drop. 297 00:15:25,080 --> 00:15:28,760 Speaker 1: Prep works by setting up fortified walls around the cell 298 00:15:29,080 --> 00:15:32,760 Speaker 1: that HIV is trying to infect, so those spike proteins 299 00:15:32,880 --> 00:15:35,800 Speaker 1: can't bind and infect and as a result of that, 300 00:15:35,920 --> 00:15:37,960 Speaker 1: they can't replicate inside the whole cell. 301 00:15:38,520 --> 00:15:41,560 Speaker 4: It's great because if people take it every day, then 302 00:15:41,600 --> 00:15:44,760 Speaker 4: it reduces their exposure to infection. However, they have to 303 00:15:44,800 --> 00:15:47,600 Speaker 4: take it every day, simply stated. You can think about 304 00:15:47,600 --> 00:15:50,400 Speaker 4: it like something such as birth control. Birth control, like 305 00:15:50,400 --> 00:15:52,320 Speaker 4: if you're taking a pill, it's usually like ninety to 306 00:15:52,400 --> 00:15:54,840 Speaker 4: ninety seven percent effective if you take it according to 307 00:15:54,920 --> 00:15:57,320 Speaker 4: the instructions. The instructions say that you have to take 308 00:15:57,360 --> 00:16:00,080 Speaker 4: the pill at the exact same time every day in 309 00:16:00,160 --> 00:16:02,360 Speaker 4: order for it to reach the efficacy For the people 310 00:16:02,400 --> 00:16:05,200 Speaker 4: that use this type of contraceptive, how many times have 311 00:16:05,240 --> 00:16:08,000 Speaker 4: you not taken it at two two pm every day? 312 00:16:08,040 --> 00:16:09,240 Speaker 3: How many times have you missed a day? 313 00:16:09,240 --> 00:16:11,320 Speaker 4: If you think about vitamins, do you take your vitamins 314 00:16:11,320 --> 00:16:12,200 Speaker 4: every day regularly? 315 00:16:12,240 --> 00:16:13,800 Speaker 3: Do you go to the gym every day regularly? 316 00:16:13,840 --> 00:16:16,680 Speaker 4: All of these behavioral things that we know will positively 317 00:16:16,680 --> 00:16:19,800 Speaker 4: impact our health and our longevity, our quality of life. 318 00:16:19,880 --> 00:16:21,000 Speaker 2: Remember T T shoes? 319 00:16:24,360 --> 00:16:26,720 Speaker 1: Yeah, if you didn't hear the shoe story, go back 320 00:16:26,720 --> 00:16:28,960 Speaker 1: and listen to the lab right before this one. 321 00:16:28,880 --> 00:16:39,800 Speaker 2: Where we talk about, you know, forgetfulness consistency. Taking a 322 00:16:39,800 --> 00:16:41,440 Speaker 2: pill every day for the rest of your life can 323 00:16:41,480 --> 00:16:43,440 Speaker 2: be costly, Like a lot of people might not have 324 00:16:43,480 --> 00:16:46,680 Speaker 2: access to the resources or insurance that allows them to 325 00:16:46,680 --> 00:16:48,080 Speaker 2: get that medication consistently. 326 00:16:48,360 --> 00:16:50,680 Speaker 4: So we need a vaccine because a vaccine will go 327 00:16:50,680 --> 00:16:53,880 Speaker 4: into healthy individuals before they have any potential for exposure 328 00:16:54,040 --> 00:16:56,280 Speaker 4: and prevent them from being infected. You take the full 329 00:16:56,320 --> 00:16:59,200 Speaker 4: regiment of the vaccine, then you're prevented from ever getting 330 00:16:59,280 --> 00:17:02,080 Speaker 4: the virus. And so even if there's a few instances 331 00:17:02,080 --> 00:17:04,760 Speaker 4: of breakthrough, majority of the population will be protected so 332 00:17:04,760 --> 00:17:07,200 Speaker 4: they will never have to do that everyday treatment or 333 00:17:07,240 --> 00:17:09,919 Speaker 4: every day preventative pill. I'm really interested in where we 334 00:17:09,960 --> 00:17:12,800 Speaker 4: are now, as we learn with COVID, getting a vaccine 335 00:17:12,800 --> 00:17:15,399 Speaker 4: approved and on the market can be a very involved, 336 00:17:15,560 --> 00:17:17,840 Speaker 4: expensive and time consuming process. 337 00:17:17,960 --> 00:17:21,359 Speaker 1: Okay, So once a novel or new vaccine candidate is 338 00:17:21,400 --> 00:17:24,520 Speaker 1: developed in a lab, it goes through a really rigorous 339 00:17:24,560 --> 00:17:28,199 Speaker 1: evaluation process where it's tested for safety and effectiveness in 340 00:17:28,280 --> 00:17:31,760 Speaker 1: humans before it's licensed for use. And this includes several 341 00:17:31,760 --> 00:17:35,119 Speaker 1: different phases of clinical trials. You probably remember hearing about 342 00:17:35,119 --> 00:17:37,679 Speaker 1: that with the COVID vaccines too, So we wanted to 343 00:17:37,720 --> 00:17:40,280 Speaker 1: know from doctor Daniels, where are we at in terms 344 00:17:40,359 --> 00:17:44,560 Speaker 1: of progress towards an effective HIV vaccine? Are we close? 345 00:17:44,960 --> 00:17:47,320 Speaker 4: Learning from my predecessors, I'm not going to stay a timeline. 346 00:17:47,359 --> 00:17:49,879 Speaker 4: What I will say is that we are having promising 347 00:17:50,080 --> 00:17:52,800 Speaker 4: results from studies that suggest that we may be on 348 00:17:52,840 --> 00:17:55,080 Speaker 4: the right path. I'm sure it's hard to predict because 349 00:17:55,160 --> 00:17:58,480 Speaker 4: historically the HIV vaccine has been pretty elusive. 350 00:17:58,640 --> 00:18:01,840 Speaker 1: In nineteen eighty four, when HIV was first determined as 351 00:18:01,880 --> 00:18:04,960 Speaker 1: the cause of AIDS, the United States Health and Human 352 00:18:05,000 --> 00:18:09,119 Speaker 1: Services Secretary Margaret Heckler said that she believed a vaccine 353 00:18:09,119 --> 00:18:11,920 Speaker 1: for HIV would be ready for testing in two years. 354 00:18:12,160 --> 00:18:14,920 Speaker 2: There have been multiple trials in different phases through the years. 355 00:18:15,200 --> 00:18:18,520 Speaker 2: Most notably, vax Gen got FDA approval for the first 356 00:18:18,600 --> 00:18:22,119 Speaker 2: large scale Phase three clinical trial of an HIV vaccine 357 00:18:22,160 --> 00:18:25,480 Speaker 2: in nineteen ninety eight. That vaccine was called vax zero 358 00:18:25,560 --> 00:18:29,400 Speaker 2: zero four, but it ultimately failed. For a deep dive 359 00:18:29,440 --> 00:18:32,000 Speaker 2: on that, check out the June second episode of Gimletz 360 00:18:32,040 --> 00:18:35,159 Speaker 2: podcast Not Pasted It, which really breaks it down. 361 00:18:35,000 --> 00:18:37,080 Speaker 1: But there was a clinical trial in two thousand and 362 00:18:37,160 --> 00:18:38,480 Speaker 1: nine with positive results. 363 00:18:38,800 --> 00:18:41,840 Speaker 4: So today the only effective trial has been by the 364 00:18:42,000 --> 00:18:44,280 Speaker 4: r one four to fourth trial that was done in 365 00:18:44,359 --> 00:18:47,800 Speaker 4: humans and it led to about thirty percent protection. 366 00:18:48,160 --> 00:18:51,199 Speaker 1: The RV one forty four trial was a partnership between 367 00:18:51,320 --> 00:18:54,840 Speaker 1: the United States and the Royal Thai governments. From two 368 00:18:54,880 --> 00:18:57,520 Speaker 1: thousand and three to two thousand and six, over sixteen 369 00:18:57,600 --> 00:19:01,800 Speaker 1: thousand people volunteered to receive a two vaccine combination, one 370 00:19:01,920 --> 00:19:04,639 Speaker 1: prime and one boost. When the results were released in 371 00:19:04,640 --> 00:19:07,600 Speaker 1: two thousand and nine, with a thirty two percent efficacy 372 00:19:07,640 --> 00:19:11,280 Speaker 1: rate for preventing HIV, it became the only trial that 373 00:19:11,320 --> 00:19:14,800 Speaker 1: had any evidence of effectiveness and remains so to date. 374 00:19:15,119 --> 00:19:18,399 Speaker 1: You need a much higher efficacy rate to get approval. 375 00:19:18,680 --> 00:19:22,280 Speaker 1: But there were some really valuable learnings from this trial that. 376 00:19:22,240 --> 00:19:24,280 Speaker 4: Enabled us to learn a lot about what type of 377 00:19:24,320 --> 00:19:26,280 Speaker 4: responses are necessary. So that's kind of when we learned 378 00:19:26,280 --> 00:19:29,000 Speaker 4: a lot of information about the fact that neutralizing and 379 00:19:29,119 --> 00:19:32,199 Speaker 4: non neutralizing antibodies contribute to the response. And people have 380 00:19:32,240 --> 00:19:35,640 Speaker 4: followed up on the things that were learned from that 381 00:19:35,800 --> 00:19:38,880 Speaker 4: study in terms of like more recently, there are preliminary 382 00:19:38,880 --> 00:19:41,639 Speaker 4: results from a lab from scripts that show that they 383 00:19:41,640 --> 00:19:45,000 Speaker 4: were able to elicit precursor antibodies that may have that 384 00:19:45,160 --> 00:19:47,720 Speaker 4: breath and potency that we want to listit pre neutralizing 385 00:19:47,760 --> 00:19:50,919 Speaker 4: antibodies and ninety seven percent of their participants, and so 386 00:19:51,040 --> 00:19:53,840 Speaker 4: that's really promising. It's not a final result, you know, 387 00:19:53,840 --> 00:19:57,159 Speaker 4: it's not we elicited neutralizing antibodies, but something that has 388 00:19:57,200 --> 00:20:00,880 Speaker 4: the potential to become a neutralizing antibody. But if that happens, 389 00:20:01,080 --> 00:20:02,680 Speaker 4: then that would jump to the front of the line 390 00:20:02,680 --> 00:20:03,480 Speaker 4: as a candidate. 391 00:20:08,680 --> 00:20:12,120 Speaker 2: So this feels like we are trending in the right direction. 392 00:20:12,560 --> 00:20:15,840 Speaker 1: Yes, all of this information from doctor Daniels has made 393 00:20:15,880 --> 00:20:18,080 Speaker 1: me very excited about the possibilities. 394 00:20:18,119 --> 00:20:20,440 Speaker 2: But I think if we've learned anything over the past 395 00:20:20,440 --> 00:20:23,639 Speaker 2: two years, it is that we are not blank canvases 396 00:20:23,880 --> 00:20:27,400 Speaker 2: for scientific advances, and that it is going to take 397 00:20:27,520 --> 00:20:32,119 Speaker 2: a lot of understanding of social dynamics and just situating 398 00:20:32,200 --> 00:20:34,960 Speaker 2: this research in the context of what's happened before and 399 00:20:35,000 --> 00:20:35,959 Speaker 2: what's happening today. 400 00:20:36,200 --> 00:20:38,840 Speaker 1: Right. I think that is such a great point because 401 00:20:39,080 --> 00:20:42,480 Speaker 1: with all that we knew before the pandemic hit, a 402 00:20:42,480 --> 00:20:45,040 Speaker 1: lot of us thought that once the vaccine came out 403 00:20:45,080 --> 00:20:47,399 Speaker 1: that everyone would be willing to take it, and that 404 00:20:47,560 --> 00:20:50,160 Speaker 1: wasn't the case. So when I think about the HIV vaccine, 405 00:20:50,240 --> 00:20:54,440 Speaker 1: I wonder what pushback there might be from the general population. 406 00:20:54,920 --> 00:20:57,720 Speaker 2: Yes, and you know, even though it is a short history, 407 00:20:57,720 --> 00:21:02,080 Speaker 2: it is a very complex history, full of medical neglect 408 00:21:02,359 --> 00:21:06,320 Speaker 2: and mismanagement in the early stages by research institutions, and 409 00:21:06,359 --> 00:21:09,800 Speaker 2: so I think there is a lot to unpack and 410 00:21:09,960 --> 00:21:13,360 Speaker 2: even just day to day general rumors that we kind 411 00:21:13,359 --> 00:21:15,520 Speaker 2: of mentioned at the top of the episode, how will 412 00:21:15,680 --> 00:21:19,200 Speaker 2: that affect how people receive new advances as it relates 413 00:21:19,200 --> 00:21:27,720 Speaker 2: to HIV. So it's time for one thing. I want 414 00:21:27,720 --> 00:21:29,080 Speaker 2: to know what's been on your mind or what you're 415 00:21:29,080 --> 00:21:29,680 Speaker 2: loving this week. 416 00:21:29,720 --> 00:21:32,800 Speaker 1: TT For me around this time of year, I think 417 00:21:32,880 --> 00:21:35,080 Speaker 1: the fields are always the same, and so my one 418 00:21:35,119 --> 00:21:37,960 Speaker 1: thing this week is friendship. This time of year always 419 00:21:38,000 --> 00:21:40,399 Speaker 1: feels difficult for a lot of people for a lot 420 00:21:40,440 --> 00:21:42,560 Speaker 1: of different reasons. Some people are far away from the 421 00:21:42,560 --> 00:21:44,800 Speaker 1: people that they love, some people have lost people that 422 00:21:44,840 --> 00:21:49,200 Speaker 1: they love. And I think that friendship, family, family, whatever 423 00:21:49,359 --> 00:21:52,360 Speaker 1: you want to call it, your chosen family, I think 424 00:21:52,400 --> 00:21:55,560 Speaker 1: that it's always super important to tap into those networks. 425 00:21:55,600 --> 00:21:58,439 Speaker 1: And so that's what's been getting me through this week, 426 00:21:58,640 --> 00:22:01,240 Speaker 1: is my friends and my family. So that's my one thing. 427 00:22:01,440 --> 00:22:03,040 Speaker 1: I love it. What's your one thing? Ze? 428 00:22:03,400 --> 00:22:06,160 Speaker 2: My one thing this week is kind of along those 429 00:22:06,160 --> 00:22:08,359 Speaker 2: same lines. I've been doing a lot of reflection and 430 00:22:08,400 --> 00:22:12,560 Speaker 2: having all the feels, and I've been using these prompts 431 00:22:12,600 --> 00:22:17,440 Speaker 2: called moonless and l I S t s.
