A smallpox (MVA) vaccination is being offered to people who are most at risk to help protect them against monkeypox. As monkeypox is caused by a virus similar to smallpox, vaccines against smallpox are expected to prevent or reduce the severity of the monkeypox infection. The Joint Committee on Vaccination and Immunisation (JCVI) has recommended using the MVA vaccine more widely in those at risk to help also reduce spread of the infection. There is a limited supply of the MVA vaccine so, initially, one dose is being offered to those at highest risk. As more vaccine supplies become available, more people will be offered the first dose of the vaccine. Additional supplies are expected soon and those next in line will be offered the vaccine as soon as it becomes available.
