How effective is PrEP at preventing HIV?

When taken correctly, PrEP is extremely effective, reducing the risk of contracting HIV by over 99%. The effectiveness of oral PrEP is directly linked to your adherence. It is a reliable and essential prevention tool.

The key: taking the treatment as prescribed

Studies show that protection is at its maximum (over 99%) for people who take their treatment rigorously (every day or according to the recommended schedule). Poor adherence, such as frequently missed doses, significantly reduces this effectiveness.

A new option: injectable PrEP

Injectable PrEP is a new option that provides constant protection without having to think about taking pills. An injection every two months protects you at all times.

PrEP: one tool in a global health strategy

While highly effective against HIV, PrEP should be part of a comprehensive prevention approach that includes:

• Regular screening for other STIs.
• Prioritizing Condom use depending on the context.
• Vaccination (hepatitis B, HPV).
• The knowledge of your partner's status, including that U=U (Undetectable = Untransmittable): a person living with HIV on effective treatment does not transmit the virus.
