Can someone knowledgeable provide more details about the "tri-specific" nature of the attack and what effects this might have on the selective resistance of the remaining strains? (e.g. is it something that would take three simultaneous mutations to overcome, thus being much less likely than any resistance that only takes one, due to HIV's incredibly high mutation rate, though those that do achieve all three would st…

I cannot personally do so, but I know who can and almost certainly will. The 'This Week In Virology' podcast. It's run by the head of the Columbia University virology department and a few other respected researchers in the field and is an absolutely phenomenal resource whenever there is news about virology. It doesn't look like they've covered this yet (too new) but I expect it to feature large in their next episode.…

This is why I love HN. Thanks for the resource!

My friends weren't wrapping it when I was in uni 6-10 years ago because every girl was on birth control.

I am gay so I have used condoms my whole life but my straight friends routinely go out and have unprotected sex all the time, I'd say about 5% of my straight friends consistently use condoms.

It's a design problem. Sex with condom sucks. Non-condom sex is 10x better.

The real solution will be when you have male birth control available as well; and then it comes down to only having sex with people you trust. I great partner is better than a bunch of lousy partners anyways.

Well, 99% means eradication of the virus very quickly. People won't become totally sexually irresponsible after the preventive shot, because there are many other hard to cure STDs now, especially as antibiotics are not as potent as they use to be, so i think there is no threat of 1960s style of unprotected sex wave.

You always have the risk of undesired pregnancy and the best cure for that is the condom, since birth control pills are basically hormone bombs, not very healthy for women in the long run, or you could undergo surgery, which is invasive and not without peril. So just use the condom already, those minty ones are actually cool.

And if we don't have "sexual freedom" it's probably because there are really good reasons for it. We shouldn't dismiss taboos without considering that some of them is why we've survived for so long.

It has never been quick. > Without treatment, average survival time after infection with HIV is estimated to be 9 to 11 years, depending on the HIV subtype https://en.wikipedia.org/wiki/HIV/AIDS#Prognosis You may be thinking of the ~1 year survival times after an AIDS diagnosis, but HIV is usually latent for a decade after initial infection.

In the 80s HIV wasn't really diagnosed until it had reached the AIDS level, was it? AIDS itself was first diagnosed in 1981 and HIV wasn't isolated until 1983 and didn't have that name until 1986. I've tried to do a brief search for earliest HIV (non-AIDS) diagnosis, but many websites use AIDS and HIV interchangeably.

Sure, but vkou didn't say "being diagnosed with AIDS was a quick death sentence" Importantly, you could be practicing very unsafe sex for a decade with no apparent consequences, which is not what one would conclude from vkou's comment.

In the 1980s, getting HIV was a quick death sentence. In the 2010s, getting HIV means that you are likely to live until... Your 70s. (Assuming you have access to medication.) The problem is that you need to take expensive medication for the rest of your life. And that you can infect other people.

To be fair, "getting HIV" wasn't really a thing in the dark days. You found out when you developed AIDS, because some weird opportunistic thing popped up. Pre-AIDS diagnosis came along after an awful lot of people died slowly of things that folks ordinarily don't get or don't die from.

As someone who came of sexual age in the 90s, between HIV and getting someone pregnant I was (and still would be - I'm married now so...) terrified of sex without a condom.

Hopefully it's cheap and/or Bill Gates starts throwing money into producing it if it passes clinical trials. I have a feeling that Africa is where AIDS does the most damage, and I doubt they can afford the $1000/mo. it will certainly cost in the States.

Not that it helps Africa but in the US for a drug like Truvada (PrEP) it costs ~$1500/mo on insurance but they offer a copay card that covers $3600/yr which is enough to hit my deductible at least so after 2 months I only pay $30/mo but in practice I don't pay a dime because the copay card covers it all.

Drugs are cheaper and largely subsidized by governments with high incidence of HIV.

*I'm South African, antiretrovirals are free.

Don't they have the HPV vaccine Guardasil?

Gardasil gives immunity to a few different strands of HPV, notably the most dangerous ones in terms of causing cancer risk. I do not know if it is reasonable to expect we will ever be able to totally eradicate all strains of HPV. Luckily most strains are, like most strains of herpes, innocuous. That's how they manage to infect the vast majority of the populace in the first place.

As of a few years ago, a new variety of Gardasil, called Gardasil-9 was approved by the FDA and it induces immunity against more varieties.

Are you implying that unprotected sex is bad in itself?

Edit: It was an honest question.

If that's the way you want to live your life, it is fine. But don't try to impose your ideas to other people.
