Safer Sex After Starting PrEP: Practical Habits That Still Matter

PrEP is a powerful HIV prevention tool. But it's not a free pass or a one-stop solution — it's one part of a broader, personal protection strategy.

Regular STI testing

PrEP monitoring already includes an STI test every three months. That's not just a bureaucratic requirement — it's one of the most important parts of a safer sex approach for people on PrEP. Early detection means early treatment, and less chance of passing anything on.

Vaccinations

For sexually active people, several vaccines are worth considering:

• Hepatitis A and B: Recommended for MSM, and often part of the PrEP preparation process.
• HPV vaccine: Protects against certain precancers and genital warts — also recommended for adults up to a certain age in Germany.
• Mpox (monkeypox): Since the 2022 outbreak, vaccination is recommended for MSM at elevated risk in Germany and is available in many regions.

Talking with partners

It doesn't have to be a big conversation — but bringing up HIV status, PrEP, and testing can give both parties a sense of security. "I test regularly" or "I'm on PrEP" is a form of care that many people find reassuring.

PEP — the emergency option

PEP (post-exposure prophylaxis) is an emergency measure if there's been a specific risk of HIV exposure and PrEP was not in place or not taken correctly. PEP must be started within 72 hours and is not a substitute for PrEP.

The full picture matters

PrEP, regular testing, vaccinations, open communication — together these make up a protection package that works. No single element needs to be perfect for the overall picture to be good.
