The number of gay and bisexual men in France at enough risk of HIV to benefit from PrEP is about 142,000, the country’s premier PrEP researcher, Professor Jean-Michel Molina, told the 19th European AIDS Conference (EACS 2023) in Warsaw last Saturday. Even though this represents only 0.6% of the adult male population, it is still many more than the 42,000 men who are actually taking PrEP – 29.5% of those in need of it.
