Well, that is what I thought when this whole PrEP fad was being announced as sex without the risk of getting HIV. Virus are tricky organisms they know how to adapt.
Your article says nothing about PrEP. That is just something you make up about it because you have an anti PrEP agenda.
The way that PrEP works is that any virus entering the blood stream is killed before it can establish these hidden reservoirs.
Nothing new or groundbreaking in that article.
PrEP is scientifically, clinically, statistically and practically proven to work. No need to keep beating a dead horse anymore.
