Moderna Will Start Its First Human Trials of an mRNA Vaccine for HIV (cnet.com) 152

CNET reports: Using the same mRNA technology that broke the mold with effective COVID-19 vaccines, Moderna has developed two vaccines for HIV. The first phase of testing for both could begin as early as Thursday, according to a post on the National Institutes of Health website for clinical trials. Phase 1 of the vaccine trial will test the vaccines' safety, as well as measure immunity and antibody responses. If the vaccines prove to be safe, they'll need to go through additional testing for researchers to determine how effective they are...

There were 37.7 million people living with HIV globally in 2020, according to United Nations data.

"There's a pressing need for new ways to prevent infection from viruses like HIV and influenza that conventional vaccines have struggled to address and to treat rare genetic diseases and cancers that kill millions each year," writes a reporter at Axios. "Vaccines and therapies based on messenger RNA hold promise as a solution."

      There are already medications that offer protection against HIV and trials of giving them to people who are deemed to be at-risk have been done.

      These days most of the infections are due to either sex work or lack of access to education and healthcare. A vaccine would certainly help if it was cheap and widely distributed, but given that there is a lack of will to do more with what we already have I'm not sure that will happen.

    The HIV vaccine is likely to be safe, but unlikely to be effective, based on past experience with HIV vaccines.
    If an HIV vaccine were as easy to build as a coronavirus vaccine, then we'd have had one long ago.

      mRNA is about speed of delivery.

      some medicines are not viable strictly from a business or logistical perspective.

      lets take cancer for example. ive heard each individuals cancer is unique to the individual and maybe even changes while inside the person. so that treating with anything other than surgery or radiation is a moving target. you cannot stand up a general solution that can be turned into a viable business that can pay for its research, delivery, qa and lawsuits etc.. with solutions that are unique to every person.

      but the covid vacinne for example they were able to sequence the virus and then produce the solution in a very quick turnaround.

      it hints at a future where they diagnose you with some cancer on day 0 and then run your blood through the sequencer on day 1 then send plans for the tailored vacinne or medicine on day 2 and on day 3 you back in the office getting the first of your shots.
      • ive heard each individuals cancer is unique to the individual and maybe even changes while inside the person. so that treating with anything other than surgery or radiation is a moving target.

        It is unique, but they all share similar characteristics. For example, every cancer has a modification to disable the p53 gene in some way. Or many breast cancers are heavily dependent on estrogen. Medicines target those common characteristics.

        When we talk about having a tailored treatment for cancer, we mean diagnosing the common characteristics of your particular cancer, and giving you a treatment based on your cancer's particular characteristics. It doesn't mean you will get a vaccine no one has ever had

Part of personalised medicines aim is to actually characterise the mutations in a cancer, and then chose drugs that can most effectively target those mutations. What happens though is the drugs are effective but often the cancer can mutate around it.

          My (non-expert) opinion is that there will be multiple answers, depending on the cancer. Some will be combinations of small-molecule drugs, Others will activate the immune system...you could call those vaccines, but I don't expect them all to work in the same way. And sometimes you'll need a combination of both. And sometimes nothing will work, even in the far distant future. Well, I suppose you could go for cryo-suspension or uploading in the far *enough* future, but nothing short of that.

      Past experience with HIV vaccines is likely to be inapplicable to predicting success here. mRNA vaccines utilize an entirely different mechanism than conventional vaccines, so you are comparing apples and oranges here.

      And really, what makes you think that building the coronavirus vaccine was easy? The mRNA covid vaccines were built off of years of research into mRNA vaccine development. The fact that they are holding up to what might be their first really large scale rollout is a strong indicator that there is good reason to be optimistic.

      • The mRNA is a method of delivering the proteins to the body. How does that make an HIV vaccine easier?

        The Coronavirus vaccine was easy because within two years of it emerging, we already have several different vaccines, both traditional style and innovative types. We even have a DNA vaccine now.

          It does, by a lot. When you introduce proteins directly into the blood .. and they are floating around in the bloodstream, guess what happens? Your APCs grab them ... and present it via the MHC II pathway to who? CD4 T-cells. Gee, I'm sure HIV will quiver in its boots about that. Oh wait, let's see .. who are HIV's favorite cells? Yup .. ye olde CD4 T-cells. The only way your CD8 cells get invited to the party is via the cross-presentation pathway, which let's admit it sucks.

          When proteins are introduced by the mRNA vaccine it is processed such that both MHC I and MHC II systems present the proteins. That means, both CD8 and CD4 cells are educated. CD8 T-cells can kick HIV's ass (Reference: https://www.nature.com/article... [nature.com] )

Traditional ones have the benefit of close to 20 years of study on how to make vaccines specifically for coronaviruses on the backs of the SARS outbreak in 2002 and MERS outbreak in ... guessing I think it was around 2010. We've been studying the spike proteins and how they work for half a century now.

      • True, I've heard the researcher interviewed who developed the mRNA technology and she said that for years her work was disregarded as useless and pointless and was scoffed at until she proved that mRNA could be used to 'program' cells to produce just about any substance you wanted them to, theoretically. It was almost pure luck that the technology was recognized as useful when it was.

          I certainly help pay for both research (via my tax dollars) and treatment (via both my tax and insurance dollars), and I think that if these vaccines have done well in non-human trials, then it will be an excellent use of my money to go to human trials. Even if it doesn't work, we'll learn a lot.

          I don't (as far as I know) know anyone with HIV, but it's a nasty and expensive illness that really needs a vaccine, both from an economic and from a moral PoV.

    • but unlikely to be effective As it is an mRNA bases vaccine it is rather safe.
      Effectiveness of previous vaccines and therapies is hampered by the fact that the virus mostly infects T-cells.
      The mRNA vaccine will reproduce in EVERY cell. So you have a high load of anti-genes (the spike proteins of the HIV-virus (yes, I know V + virus ... kind of redundant)) in your blood stream, much higher than a HIV infection would give you. And the main effect is: your body is building antibodies against that anti-gene.

      Don't expect this to enable folks to put HIV and AIDs behind us. All vaccines have a rate of bad side effects, and those who don't consider themselves at risk will refuse to take them. And this is actually a somewhat reasonable approach as HIV is usually containable by behavioral rules, and if you are already following those rules you are almost always safe. It will be like the vaccine against cervical cancer (caused by a virus) that needs to be taken before you are exposed to the virus...so parents refu

        We had side effects as in: catching the real disease in Africa in the 1950s - because the supposed weakened/half dead polio viruses used for the vaccine: were not dead.

        The so called "side effects" in Corona vaccines are not side effects. That is a stupid misnomer of the industry or the health authorities: they are the expected effect.

              An allergic reaction is a side effect. Heart palpitations is a side effect. There are others. Every vaccine has some that affects some group of the population. If you disagree, give me even one counter-example.

    The problem with HIV is that the wily thing keeps mutating -- I mean coronavirus hardly mutates .. whereas HIV is so susceptible to APOBEC3 base editing and carries with itself such a shitty polymerase such that most copies of itself are flawed. Unfortunately, that also means it can occasionally get lucky and win the immunity evasion lottery. But I suppose if they could keep providing booster shots that might help. Ultimately though, the cure will have to use a combined immune + gene-therapy approach .. in my opinion. 1. Train the immune system using a vaccine, but then also 2. delete the provirus (meganucleases show promise) and 3. gene-edit the HIV entry receptors. I believe all three methods will have to be used simultaneously for a cure, because each one alone may be insufficient to get to a 99.9% cure rate.

      That's the big plus of mRNA over traditional vaccines. The mRNA vaccine can be far more specific to one protein. There's one protein on HIV that can't mutate much - the one it uses to enter human cells. When that one mutates enough, you get virus that can't infect anything.

      So, an mRNA vaccine targeting that protein makes the mutation problem much less of a problem. It's extremely unlikely that the virus would be able to gain a mutation that avoids the vaccine while also remaining effective in matching o
