HIV is incredibly sophisticated. It's actually kind of amazing how effective it is. I mean obviously the resulting disease is bad, no question. You can still appreciate the sophistication.

HIV has resisted efforts to develop a vaccine for 30+ years at this point.

I am already beginning to wonder if the 2020s will be the story of the social transformation caused by mRNA vaccines. An effective and relatively cheap HIV vaccine will be huge.

Apart from Covid and HIV, mRNA is going to have a huge effect on the flu vaccine too. For anyone who doesn't know, predictions are made about what flu strains will dominate the coming winter 4-6+ months ahead of time and the vaccine is made from that. Those predictions may not be accurate, which largely explains the variance of efficacy. mRNA has the potential to reduce that down to 1-2 months so you can potentially react to the actual dominant strains.

Cancer of course isn't a single disease. Even something like lung cancer are a collection of different diseases. But some cancers are caused by viruses. A notable example is cervical cancer where it seems like most cases are caused by HPV strains. Australia is on track to essentially eliminate cervical cancer by 2035 [1]. To be clear, this isn't an mRNA vaccine.

But mRNA vaccines may greatly reduce the time required to develop a vaccine and make it possible to eliminate whole classes of diseases.

This is all super-exciting.

Agreed this very exciting. Malaria is also being targeted using the same technology. BioNTech announced they were working on it last month and some results[1] in mice are already looking promising.

> But some cancers are caused by viruses.

Note that mRNA technology is not limited to viruses. The cancer vaccine is actually a misnomer as it is actually a personalized treatment for people who already have cancer [1]:

> The cells from the patient's tumor are analyzed, and genetic sequencing is used to identify twenty neoantigen epitopes that may elicit the strongest immune response in the patient. The sequences encoding the twenty patient-specific epitopes are transcribed and loaded onto a single mRNA molecule. [...] This leads to an induction of both cytotoxic T-lymphocyte (CTL)- and memory T-cell-dependent immune responses that specifically target and destroy the patient's cancer cells that express these neoantigens.

BioNTech has actually started Phase 2 trials for a mRNA-based cancer therapy [2].

What's funny is the US initially only vaccinated women against HPV because "men can't get cervical cancer". Then it turned out lots of men were getting oral/throat cancers from oral HPV acquired from oral sex. Oops!

Re:Moderna Is About to Begin Trials for HIV Vaccine by inasio on Tuesday August 17, 2021 @02:12PM (#28213032)
The bigger issue was anal cancer among men that have sex with men, if I remember correctly the risk was around 100x than in the general population, and also completely preventable by the HPV vaccine.

Source for this, and the amount of time that we were only vaccinating women? If it was just a year or so, that's a very different story from decades.

I recall there being a sudden, loud push 10ish years ago, for everyone to get the HPV vaccine.

There were some anti-vax arguments against it for the same reason as there's resistance to sex ed; but no "men can't get cervical cancer" arguments, that I recall.

As of 2017 WHO was still recommending prioritizing girls under 15 for vaccination: https://www.who.int/immunization/policy/position_papers/pp_h...

> Vaccination of secondary target populations e.g. females aged ≥15 years or males, is only recommended if feasible, affordable, cost-effective and does not divert resources from vaccinating primary target population or from effective cervical cancer screening programmes.

I think the tone I read implied into your post was that it was something malicious or arrogant. "Don't protect the men because they don't need to care about giving it to women", followed by "oh noes, men can get sick too! Better protect them!" rather than a resource allocation problem, as the quote is arguing.

Building out the capacity to manufacture and distribute ten billion doses of new vaccines as quickly as we can validate their safety and efficacy would also be quite the feat.

It's nice for a first-world citizen that we were getting vaccinated against a new disease 12-18 months after it was first discovered, but with a big enough supply chain we could potentially be aiming to finish a world-wide vaccination campaign in 6-12 months, before we begin running up against the limits of our current methodologies for clinical trials.

In the 90s, sure. Between treatment so effective that you can't pass it on and PreP, the days of HIV is over anyway. Vactination might be a bigger deal in poor countries, but they are also the countries that can least afford it.

If they can cure HIV, that would be another thing.

If all mRNA have side effects like the current crop of COVID vaccines I’m honestly not sure they are worth it as a seasonal flu shot.

I’m not talking about the scare mongering of long term effects. Just the immediate.

The day after my second moderna shot was worse than any flu I can remember and many of my friends in their 20s and 30s had to take a day off after their shot. I know several people in their 60s who had to take several days to a week in bed from vaccine side effects.

That’s fine for ending a pandemic or curing HIV, but for seasonal flu?

In terms of lost labor days, my anec-data points to this vaccine seeming worse than a seasonal flu.

Re:Moderna Is About to Begin Trials for HIV Vaccine by Broken_Hippo on Tuesday August 17, 2021 @12:31PM (#28211738)
I don't know. The last time I had a seasonal flu, I was sick for a week. I cried because I needed to do laundry and simply didn't have the energy and I ate poorly - I lived alone at the time. All of my energy went to surviving work.

Compared to having a sore arm for a couple of days? Or even getting sick for a day or two - at a time I can choose - to just not deal with getting sick later on? Sure. And I'm awfully sure that the flu kills more than the vaccine for it. So many complications for so many people.

And to be fair: The folks you knew in their 60's had an unusual reaction. Older people with their aging immune systems are actually more likely to get little to know side effects to vaccines - younger folks tend to get more. The same goes for folks that are genetically female: You tend to get more side effects (they think this is because so many immune genes are on sex chromosomes, and women have more genes here.).

And to be fair: Taking a day off of work when you are sick isn't such a big deal if you live somewhere with labor protection laws that allow you sick days. It is a little less of a big deal if you live in the US and get paid sick time, but a lot of folks just don't have this so it makes being sick after a vaccine a bigger deal that it should be.

Re:Moderna Is About to Begin Trials for HIV Vaccine by Kluny on Tuesday August 17, 2021 @12:19PM (#28211561)
Like you said, it's anec-data. Among my friends, two were very sleepy the following day and otherwise fine. I had a sore arm for two days, and no other effects. My parents didn't have any noticeable effects.
Re:Moderna Is About to Begin Trials for HIV Vaccine by hn_throwaway_99 on Tuesday August 17, 2021 @12:30PM (#28211724)
But there is significant real data that the side effects from Moderna were significantly worse (but, again, not severe, and time-limited) than a flu shot.

I know this is just another anecdote, but I get a flu shot every year and have never experienced anything more than a sore arm. With 2nd Moderna dose I had a fever of 103 and was completely out of commission for 36 hours.

It's all relative. The side effects from a flu shot are mild compared to the flu. Ditto for the Moderna vaccine.

Re:Moderna Is About to Begin Trials for HIV Vaccine by CorrectHorseBat on Tuesday August 17, 2021 @12:40PM (#28211869)
I think they just took the highest dose that had acceptable side effects because they had no time to figure out the perfect dose.
Re:Moderna Is About to Begin Trials for HIV Vaccine by garenp on Saturday August 21, 2021 @11:18PM (#28262586)
This is also my thinking, and doesn't seem too implausible given that the dosage is so much higher than Pfizer (100mcg vs 30mcg). My relatives who got Moderna had similar reports to some of the posters above. I got Pfizer and barely noticed.

I've had Moderna and the flu, and they were about equally bad ("I can move, but only because I'll wet the bed otherwise, please God let me sleep so it stops feeling like my bones are dissolving") but Moderna lasted only a day whereas the flu lasted several. I think you'll struggle to argue convincingly that Moderna doesn't commonly have awful side effects :P

Re:Moderna Is About to Begin Trials for HIV Vaccine by bastardoperator on Tuesday August 17, 2021 @01:04PM (#28212184)
The question is simple, does the benefit of using said vaccine or medication outweigh the risk of not using it. In the case of covid being sick for a couple of days and a guarantee of preventing future death is better than a resulting death had the user not taken it.

I would say a couple of days of flu is vastly better than some of the other side effects I've seen with other medications. Take for instance:

- Suicidal thoughts - Abnormal heart rhythms - Internal bleeding - Cancer

At the end of the day, we rely on medical professionals to help us with these decisions and weigh the treatment of said ailments against the side effects we may incur if we do or don't take treatment. For what it's worth I've seen the opposite, most folks took the day off just in case there was a side effect, but ultimately everyone was fine. I know I scheduled my vaccine shots for a Thursday so I could have a 3 day weekend assuming I wasn't feeling ill, and I felt fine so I enjoyed my 3 day weekend.

Re:Moderna Is About to Begin Trials for HIV Vaccine by fallingfrog on Tuesday August 17, 2021 @12:17PM (#28211546)
It may be that the vaccine side effect severity is proportional to the severity of the disease it prevents.

Also, these vaccines were very rapidly developed so perhaps the next generation of them will be a bit easier on the body.

like the covid one is sold at super low prices compared to what would normally be possible

To me the "coolest" feature is that it saves dormant copies in cells, so that even if there is no detectable virus in the blood, a few months after stopping taking anti-HIV drugs the virus will reappear. If you sample the virus right when the first spike reappears, you will see a bunch of different HIV virus types, essentially the history of each mutation on that person, as each virus strain saves its own copies... (soon after the strongest strain dominates)

A person with HIV will actually be infected by multiple variants simultaneously, since the virus mutates rapidly within a single host (tons of variants will be produced in a single day). So, even though the immune system will fight the virus and produce antibodies, the virus stays one step ahead. That also means that a person will not develop long-term immunity after being exposed to the live virus (and can even be infected multiple times with different variants and strains), and is the main challenge with developing an HIV vaccine.

I am no expert but my understanding is that AIDS occurs when a variant targeting receptors more specific to CD4 T-cells begins replicating (or begins replicating at too high a rate), which results in T-cell counts falling below some threshold. So a person will go through an extended period without feeling any symptoms, possibly transmitting the virus to others (hence the importance of widespread, easy access to testing), only to be incapacitated by AIDS later when the "balance" of the variants changes (assuming they do not receive HIV-suppressing medications).
