California's combination of Medi-Cal coverage, ACA vaccine mandates, and proactive LGBTQ+ clinic programming means that the core sexual health vaccine stack is accessible at low or zero cost for most residents. The hard part is knowing to ask for them—clinics will not always offer them proactively.

🔑 The HPV Window: Don't Miss It

Under the ACA, HPV vaccination is free with no cost sharing for anyone up to age 26. California's Medi-Cal extends this to age 45 for people who have not previously been vaccinated—making it one of the most generous HPV programmes in the US.

The Gardasil opportunity closes. If you are over 26 and uninsured without Medi-Cal, you will pay out-of-pocket for HPV vaccination (~$250–350 per dose, 2 doses required). This is the only vaccine on earth that actively prevents cancer. Do not put it off.

🦠 Mpox: Where to Get It in California

Following the 2022 outbreak, CDPH integrated Mpox vaccination into routine sexual health care at LGBTQ+ clinics. Stock availability has stabilized in major cities.

Primary access points:

  • SF City Clinic — walk-in vaccine appointments during certain sessions (check sfdph.org)
  • LA LGBT Center — scheduled vaccine appointments (call ahead)
  • County health departments — check your county's DPH website for community vaccine events

You need two doses, 28 days apart. After a long gap between doses 1 and 2 (e.g., during prior shortage), you do not need to restart the series. Pick up from dose 2.

🏥 Where to Get Vaccinated

In California, your best access routes are:

  1. Your LGBTQ+ clinic or FQHC: One-stop shop for the full vaccine stack. Often administered during your PrEP or STI check-in appointment.
  2. County Public Health (CDPH): Free vaccines for uninsured residents through county programs.
  3. Pharmacies (Walgreens, CVS): Hepatitis A/B and flu shots are widely available, often covered by Medi-Cal or ACA insurance with no copay.

Bring your records. If you were partially vaccinated years ago (e.g., received one dose of Hep B), bring your vaccination history. A blood titer test can confirm immunity so you don't repeat unnecessary doses.
