How effective is PrEP? (Details)
PrEP is the most safest way of HIV prevention for now. However, one has to make sure they take this pill daily to maximize the effectiveness at preventing HIV.
Unlike condoms which offer 70% safety, PrEP is safe by 99% meaning it is a better method of preventing HIV when used all the time. You can also use both methods if need be, just to increase the level of effectiveness.
In 2009, a large study showed that not only was it effective at treating HIV, but also at preventing HIV when taken every day. Since then, several studies have confirmed that it is incredibly effective at prakes into account things like missed doses, interactions with other medications a person might be taking, or other illnesses that might be present.
When we say PrEP is 99% effective, that means that when PrEP is taken every day as prescribed, it prevents 99% of the cases of HIV that would have occurred otherwise.
