Vaccination Recommendations for Men who have Sex with Men (MSM)



Hey handsome! It’s Tom of P-Town here, and as a doctor who provides care to many men in our community, I want to emphasize a crucial point: gay men often face higher exposure risks to certain infectious diseases than the general heterosexual population. This leads to broader vaccination needs. Below are the vaccinations I strongly recommend to all of my patients who are men who have sex with men (MSM) that are in addition to more routine vaccinations. Consider this your roadmap to staying healthy, protected, and ready for all the fun!


1. Monkeypox (Related to Smallpox)

Why It Matters

  • Monkeypox can spread through close contact, including sexual activity. MSM have been disproportionately affected in recent outbreaks due to frequent skin-to-skin or intimate contact.
  • The available vaccine (e.g., JYNNEOS) also provides protection against smallpox.
  • Outbreaks can quickly escalate within close-knit social networks, making individual protection key.

Risks vs. Benefits

  • Benefits: Significantly reduces the likelihood of severe disease and helps protect partners and community.
  • Risks: Mild side effects (injection-site swelling, fatigue, headache) are possible, but serious adverse events are rare.
  • Bottom Line: If you’re regularly out in crowded venues (clubs, bathhouses, festivals), I strongly recommend discussing a monkeypox vaccination series.

2. Meningitis (Meningococcal Vaccine)

Why It Matters

  • Meningococcal disease causes severe infections of the brain/spinal cord (meningitis) or bloodstream.
  • Previous meningitis outbreaks have occurred within MSM communities, especially in urban settings or among individuals with close social/sexual networks.
  • The disease can progress rapidly, sometimes leading to life-threatening complications.

Risks vs. Benefits

  • Benefits: The vaccine offers robust protection against the strains most commonly causing outbreaks.
  • Risks: Typical side effects are mild (sore arm, possible low-grade fever), and serious reactions are very rare.
  • Bottom Line: For patients—particularly those who are HIV-positive or frequently in large gatherings—I strongly recommend the meningococcal vaccine.

3. Hepatitis B

Why It Matters

  • Hep B is a liver infection spread through blood and bodily fluids (e.g., sexual fluids).
  • MSM face higher rates of transmission, and chronic Hep B can lead to cirrhosis or liver cancer.
  • Vaccination is a highly effective way to prevent long-term complications.

Risks vs. Benefits

  • Benefits: This vaccine has been around for decades with an excellent safety record. After completing the series (usually three shots over six months), protection is long-lasting.
  • Risks: Mild side effects like soreness at the injection site or low-grade fever are possible. Serious side effects are extremely rare.
  • Bottom Line: If you haven’t been vaccinated (or are unsure), I strongly recommend testing for Hep B and starting the vaccination series if you’re negative. Safeguard your liver!

4. Hepatitis A

Why It Matters

  • Hepatitis A spreads through contaminated food/water and close personal contact (it can be transmitted sexually through certain activities e.g. butt-munchin).
  • MSM communities have historically experienced outbreaks.
  • While Hep A typically causes a short-term infection, symptoms can be severe and disruptive.

Risks vs. Benefits

  • Benefits: The Hep A vaccine is extremely safe and grants long-lasting immunity.
  • Risks: Mild injection-site soreness or a brief period of fatigue.
  • Bottom Line: Often provided together with Hep B as a combined vaccine (“Twinrix”). I strongly recommend it if you haven’t received it yet, especially if you like to eat a nice peach!



5. HPV (Human Papillomavirus)

Why It Matters

  • HPV is widespread and can lead to genital warts, as well as anal, penile, and oropharyngeal (throat) cancers.
  • Gay and bisexual men have a higher risk of HPV-related anal cancer.
  • Vaccinating helps reduce the spread of high-risk HPV strains.

Risks vs. Benefits

  • Benefits: The HPV vaccine (commonly Gardasil 9) protects against multiple strains most linked to cancer and warts.
  • Risks: Possible mild side effects such as injection-site redness, swelling, or mild fever. Serious reactions are rare.
  • Bottom Line: Even if you’re older than the typical vaccination age, it’s still worth discussing the vaccine. I strongly recommend it as part of a comprehensive preventive care strategy.

6. Measles (Part of the MMR Vaccine)

Why It Matters

  • Measles is highly contagious and can spread through respiratory droplets in crowded settings (like bars, events, or festivals).
  • Outbreaks often occur when vaccination rates drop, and large gatherings increase the chance of exposure.
  • Even though measles is typically covered in childhood vaccinations, many adults either aren’t fully immunized or may not have received the recommended booster.

Risks vs. Benefits

  • Benefits: The MMR (Measles, Mumps, Rubella) vaccine is very safe and effective, reducing the likelihood of contracting and spreading measles.
  • Risks: Mild side effects such as soreness at the injection site or low-grade fever may occur; serious complications are rare.
  • Bottom Line: I strongly recommend verifying your measles (MMR) immunization status. If you’re not fully covered, make sure to get vaccinated—especially if you travel often or attend large social events.

Conclusion

When I say “vaccine up,” I mean it wholeheartedly. By staying on top of these immunizations, you’re not only protecting yourself but also helping curb transmission within our close-knit communities. If you have any concerns or unanswered questions, talk to a healthcare professional you trust—and never hesitate to advocate for what you know you need.

Remember: You deserve healthcare that accounts for the unique needs of gay men. Take charge, stay healthy, and keep on living your fabulous life.

Dr. Tom
