Pills (PrEP) protect you from HIV. Condoms protect you from fluids. But some viruses are stubborn—they live on skin, or they survive on surfaces.

Vaccines are your "Software Updates." You patch the vulnerability once, and you are protected for years (or life).

If you are sexually active with men, this is your standard loadout.

1. HPV (Gardasil 9)

The Threat: Human Papillomavirus.

  • What it does: Genital warts (unsightly, annoying) and Cancer (Anal, Throat, Penile).
  • The Myth: "It’s a girl’s vaccine."
  • The Reality: Men get anal cancer and throat cancer from HPV. It is rampant in the gay community. Guys who have not been vaccinated have especially high exposure rates.
  • The Cancer Numbers: Anal cancer is rare in the general population, but gay and bisexual men have rates approximately 20–40 times higher than heterosexual men. HIV-positive gay men face roughly 30 times the anal cancer risk of HIV-negative men, though HPV-related anal cancer is significantly elevated even in HIV-negative gay and bisexual men. Throat cancer from HPV (oropharyngeal cancer) is now the most common HPV-related cancer in men overall. All of these cancers are largely preventable with vaccination.
  • The Protocol:
    • 2 shots (if you start your series before age 15): given 6–12 months apart.
    • 3 shots (if you start at age 15 or older): given over 6 months (Day 0, Month 2, Month 6).
    • Age: Approved up to age 45. Routine vaccination is recommended through 26. Ages 27–45 who weren’t previously vaccinated should discuss it with their doctor—coverage/cost varies, but the cancer risk makes it worth the conversation.
    • Already exposed? The vaccine still provides partial protection against the strains you haven’t yet encountered. Getting vaccinated after sexually active is still beneficial.

2. Hepatitis A & B (Twinrix)

The Threat: Liver damage.

  • How it spreads:
    • Hep A: "Ass to Mouth" (Rimming). It’s in feces. Microscopic amounts are enough.
    • Hep B: Blood and semen. Highly infectious (more than HIV).
  • The Protocol:
    • Usually a combo vaccine (Twinrix).
    • 3 shots (Day 0, Month 1, Month 6).
    • Status: Once you complete the series, you are usually immune for life.
  • Note on Hep C: There is no vaccine for Hepatitis C. It spreads via blood contact (shared toys, fisting, needles, rough sex). It is now curable with a short course of antivirals, but the only protection is avoiding blood-to-blood exposure and testing regularly (every 3 months if you have higher-risk encounters).

3. Mpox (Jynneos / Imvanex)

The Threat: Painful lesions, fever, scars, and potential scarring.

  • The Reality: Still actively circulating in sexual networks globally. Spreads via skin-to-skin contact (sex, prolonged close contact). Clade II (the milder strain) remains endemic in Western networks; Clade I outbreaks have also occurred internationally.
  • The Protocol:
    • Standard (subcutaneous): 2 shots, 28 days apart.
    • Intradermal dosing is approved in some countries (smaller dose between skin layers, same schedule)—ask your clinic.
    • Effectiveness: Drastically reduces severity and transmission. Even if you catch it, your course of illness will be significantly milder.
    • Booster: If you received both doses during the 2022 outbreak, your protection is still active.

4. Meningitis ACWY & B

The Threat: Bacterial Meningitis.

  • How it spreads: Deep kissing (saliva exchange).
  • The Reality: Outbreaks cluster in festival and heavy partying scenes. It can kill within 24 hours of symptom onset.
  • The Protocol:
    • MenACWY (1 shot, booster after 5 years if risk continues).
    • MenB (2 shots, 1 month apart).

The Strategy: "Patch Tuesday"

You don’t need to get them all at once.

  1. Priority 1: Hep A/B & Mpox (The basics—highest risk for gay and bisexual men).
  2. Priority 2: HPV (The long-term investment against cancer).
  3. Priority 3: Meningitis (If you’re in the party/festival scene).

Check your records. You might have had some as a child, but immunity fades. Ask for a "Titer Test" (blood test) to see if you still have protective antibodies before re-doing the full series.
