@justatest90-0 PrEP is very expensive in Taiwan if you are not a high risk person (like say medical workers). I heard that you have to buy it in Thailand if you want it cheaper, like vastly cheaper.
Otherwise a course of prep is something like close to 1000 dollars.
But once you become positive, the government pays the costs, and first 2 years is paid for by the Taiwan's version of CDC, after that it's paid for by the national healthcare.
