This is completely inaccurate. There is PrEP that requires dosing two times a year. You can also get PEP if you engage in a risky activity without PrEP.

Yes, it exists, but how available is it really? If I recall correctly, the injections are also not very pleasant.

"Gilead sells LEN at very high prices (over $28,000 per person per year in the US), severely restricts its supply to certain countries, and refuses to sell it directly to Doctors Without Borders/Médecins Sans Frontières"

The shots are expensive, but the pills are free in the USA. They do have adverse kidney issues over prolonged use (more for some people than others).
reply
And clearly only the people in the USA matter.

Are you serious? I would bank money on PEP being practically free in sub-saharan Africa.

*PrEP

It... was, until Musk dismantled USAID and Congress defunded PEPFAR.

So many comments by people who have never stepped foot out the Global North making wild assumptions.

reply
I was explicitly referring to PEP. I'm not sure why you would make assumptions about where I have or haven't been when you have absolutely no information.

PEP remains largely free in SSA post-USAID/PEPFAR cuts.

reply
Ok... so you have to

1. Know you were exposed (many many many people don't know they're HIV+)

2. Have the means to go to a clinic within 72 hours

3. Have the social capacity to go to the clinic safely (in many parts of Sub Saharan Africa doing so would insult your partner)

PEP is an emergency drug, not a prevention at all.

reply
My understanding is PrEP is also free, but I'm less certain about that post-cuts.
reply
It is not, at all anymore.
reply
That PrEP is in some ways similar to a vaccine, and there is still a lot of value in getting a better vaccine (cheaper and/or lasting longer).
reply
Also, PrEP pills can have side effects long term. And distributing huge amounts of daily pills to remote areas of the globe is much harder than the patients getting a shot on their yearly medical visit.

> I'd also be curious to know if the combination of ART + the vaccine might cure someone of HIV. Which is also a pretty big deal.

"Cure" in the sense they could become indefinitely under detectable levels. It's worth noting that to really cure a person of HIV you'd need to remove all mutated cells.

reply
Ad-hoc use of PrEP just requires that you take a double dose 1 hour prior to potential exposure, and follow up with another double dose 24 hours later, at least with the versions commonly prescribed to sexually active groups in my area.

I agree that a vaccine is another game-changer, but it’s extremely important that we don’t spread misinformation about the efficacy and convenience of PrEP. In developed societies, it has already all but eliminated new transmissions among groups that were previously most at risk.

reply
At least 2 hours before, not 1, and preferably closer to 24 hours before.
reply
Does this double dose completely prevent infection?
reply
The evidence I’m aware of suggests that this method (on-demand or event-based PrEP) is broadly as effective as daily PrEP (though it’s not suitable for vaginal sex). I believe adherence rates are generally lower though, as people can find the instructions confusing, and it’s obviously easier to mis-dose than a daily regimen.
