No, not for all GBMSM. The dose is only changing for people under the age of 25. GBMSM who are over 25 are currently eligible for two doses of the vaccine until they are 45. The dose for this older group will not change. There currently isn’t enough evidence that GBMSM who receive their first dose of HPV vaccine between the ages of 25 and 45 will get enough protection from one dose, so this group should still have two doses.
