Mpox Vaccination Update

by Portia Jackson | Jun 22, 2023

A sustained reduction in mpox (monkeypox) case numbers across England and the success of vaccination in helping to control the outbreak means the vaccination programme is no longer needed as an outbreak control measure and it is now being wound down.

In line with updated UKHSA guidance, we will continue to offer first and second doses to gay and bisexual men, and other men who have sex with men, who are at highest risk from mpox attending iCaSH until the end of July 2023.  However, due to the 28-day interval required between between first and second dose, those receiving a first dose may not receive a second dose before the programme ends but UKHSA data has demonstrated that one dose of the vaccine offers 78% protection against the virus from 14 days after receiving it.  The second dose aims to provide longer-lasting protection.

Vaccination will be available beyond the end of July 2023 in London and people who are regularly travelling to London or abroad to have sex and who are eligible for the vaccine will be able to book a London-based appointment after the end of July using the national vaccination site finder at
