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!
