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