Sexual health vaccines for gay and bisexual men in Wales are commissioned by Public Health Wales (phw.nhs.wales). The offering is highly generous, but as with all NHS systems, you have to actively ask for them during a clinic visit.
💉 The Free NHS Wales Vaccine Stack
These vaccines are primarily administered at your LHB Sexual Health Clinic. Some may also be available via your GP.
| Vaccine | What it prevents | Welsh Eligibility | Doses |
|---|---|---|---|
| HPV (Gardasil) | Anal/throat cancer & genital warts | Free up to age 45 (MSM) | 1 to 3 |
| Hepatitis A | Liver infection (rimming risk) | Free for all MSM | 2 |
| Hepatitis B | Liver infection (fluid risk) | Free for all MSM | 3 |
| Mpox (Jynneos) | Mpox lesions and scarring | Free for high-risk MSM | 2 |
The HPV 45-Year Window
If you are a man who has sex with men, you can get the HPV vaccine for free on the NHS until your 46th birthday. It is the only vaccine on earth that actively prevents cancer.
Combined Hep A/B: Hepatitis A and B are usually administered together in a combined shot (Twinrix). It requires three doses over 6 months to give you lifetime immunity. If you drop out after dose one, you are not protected.
🦠 The Mpox Reality
Since the 2022 outbreak, Public Health Wales has integrated the Mpox vaccine into routine sexual health care. It is administered as a subcutaneous injection, and you need two doses, 28 days apart.
If you received a smallpox vaccine as a child, you still need the modern Mpox vaccine. The old childhood scar does not guarantee immunity against the current circulating clades.
🗓️ How to Claim Them
- Book a routine screen: The easiest way to get your vaccines is to ask for them during an in-person STI check or PrEP review at a physical LHB clinic.
- Call ahead: If you are booking specifically for vaccines, call the clinic to ensure you are booked into the correct nurse-led slot.
- Bring your history: If you were vaccinated in another country, bring a photo of your records. NHS Wales will not automatically know your international vaccine history.
