All the tools we have against teen pregnancy need teens making right decisions, or taking corrective actions.
If there were a pill that'd block pregnancy for X years, given at the age of Y, then parents could enforce it and teen pregnancy would be solved (also it'd be very cruel but I'm just trying to make a point so bear with me).
Going back to our topic: People could also forget PrEP, be drunk and forget to wear a condom and so on. If this vaccine (or vaccine series) creates a somewhat permanent protection, it'd make a huge difference.
The US state of Colorado provided young women free IUDs (which are reversible and can last up to eight years) with private funds, and it was wildly successful. I argue teen pregnancy is solved assuming systems remain in place for women to have robust access to contraceptives and reproductive healthcare (which is a systems problem that is never solved completely, but reliant on defending the subject system constantly in perpetuity). The current US administration is rolling back teen pregnancy prevention programs to increase fertility rates in these age cohorts, so there is clearly work ahead to maintain the progress we've made.
If you're sure you don't want kids, or more kids, a bisalp, or bilateral salpingectomy (permanent birth control, removal of both fallopian tubes), is covered by Medicaid or ACA compliant private insurance in the US at 100% with no patient cost sharing as part of the Affordable Care Act federal statute. Doesn't apply to teens imho, but provides protection for 20-39 prime reproductive age cohort for those seeking it. It also decreases the risk of ovarian cancer by 42–77% (https://doi.org/10.5468/ogs.2018.61.5.542).
HIV PrEP in the short term is solved with a twice a year injectable (lenacapavir) until improved options become available (rapid deployment and robust availability of a vaccine given to as many at risk people as possible, as soon as possible). It can be provided for as little as $40/person (HN Search: lenacapavir - https://hn.algolia.com/?q=lenacapavir).

(with all of that context shared, all vaccines and medical protocols that improve quality of life, as well as defend and empower the human, are welcome and needed, as quickly as reasonable)
I'm not following the points in the above thread.
- people need to make the right decisions to take oral or injectable reverse transcriptase inhibitors
- people need to make the right decisions to take HIV vaccines
We are comparing two tools, not tools versus discipline.
In some ways these reverse transcriptase inhibitors are like a vaccine, in that they can be taken by people who don't have HIV, for protection.
They are inconvenient, requiring regular injections every few months or timing protocols for the oral versions.
An effective vaccine that lasts years would be much more convenient.
Without a HIV vaccine, the toolkit has a gaping lack; another tool is needed!
No, nothing is being compared. The question being posed is, if there are already tools to prevent HIV transmission (condoms, drugs, etc.) and someone doesn't use them, why would they use a vaccine?
Right; that's a better framing.
1. Some people don't use tools. (For instance, we have spellcheckers, but people don't use them or ignore them.)
2. So of what use is another tool? (Why develop a grammar checker?)
See the problem? For the people who do use tools, there are useful differences among them. Some users of spell checkers will welcome the grammar checker.
Some of those who would use drugs to prevent transmission will gladly switch to the vaccine, which is more convenient for them.
But there is also this: the inconvenient drugs that block transmission are mainly used by HIV positive people and people who are exposed to them. Someone not in that situation is not going to get on a train of injections every three months. (I've never even heard of these drugs until this submission and its discussion threads.) Whereas a HIV vaccine could be something more interesting to the general population. There will likely be some people who get the vaccine who ignored the transmission-blocking drugs.
Sometimes when you add a different tool to the arsenal, non-users of the tool arsenal come around.
E.g. lots of DIY tinkerers use USB oscilloscopes, who have never owned a big one. The invention and marketing of the USB scope turned them into users. The vendors of that could have axed the idea by saying, what's the use of this idea: we already have oscilloscopes? Those who don't have them already are not going to be interested in this.
There are right tools for the right job, but also the right tools for the right people in the right circumstances.
Because a vaccine is much easier for the doctor to administer and manage. My GP won't put condoms on me but they do have a list of shots I get basically once and then never again.
