One monkey study investigated whether 16 pig-tailed macaques would be
protected from infection when given the antiretroviral drug tenofovir after intravaginal exposure to HIV type 2.1
None of the 4 macaques that started the treatment 12 hours after
exposure became infected. This was the case with the 4 macaques that
received post-exposure prophylaxis 36 hours after exposure. In the
72-hour group, one of the macaques became infected after 16 weeks. The
study concluded that early intervention with an antiretroviral form of
PEP such as tenofovir might be successful in preventing infection after vaginal exposure.

The timing of administering post exposure prophylaxis and the
duration of the course of treatment has been a highly significant factor
in all of the animal studies. HIV takes around 3 days to reach the
lymph nodes (components of the immune system), and it takes a further 2
days to reach the blood cells. There is therefore a small temporary
“window” during which the infection can be blocked. This can be seen in
another study of tenofovir post exposure prophylaxis tested on 24 macaques.2
The results showed that a 4-week regimen of tenofovir started within 24
hours of exposure completely protected the macaques from SIV. Starting
the treatment between 48 and 72 hours of infection was largely
ineffective. Treatment started within 24 hours of exposure but only administered for 3 days proved to be just as ineffective.

Còn
đoạn này nói về 1 thí nghiệm trên 24 con khỉ khác và đưa ra kết luận
nếu dùng trong vòng 24 tiếng đổ lại sẽ có hiệu quả 100%, còn nếu dùng giữa 48 và 72 giờ thì hiệu quả sẽ bị giảm đi nhiều.

Đó là các thử nghiệm trên động vật,
