9 people recommended Gardasil 9 in Hacker News comments and 2 criticized it, November 2025 to October 2026. It was recommended in 4 of 12 months, in 4 threads. It does not meet the Hacker Approved badge rule.

5 of the 9 people who recommend it commented in one thread, “HPV vaccination reduces oncogenic HPV16/18 prevalence from 16% to <1% in Denmark”. These are opinions from Hacker News comments, not medical advice. Talk to a doctor.

**Verdict:** Recommended as early protection against HPV-linked cancers, with two doses often said to give most of the benefit; the main caveat is adverse effects.
