Data from the United Kingdom Health Insurance Agency (UKHSA) reveal that as of June 20, there were 793 laboratory-confirmed cases in the UK, from 574 on June 16 – a 38% increase in just four days. While anyone can catch the virus as it is transmitted between people through close contact, the UKHSA reports that most cases have occurred in men who are gay, bisexual or have sex with men. Now the UKHSA says it is expanding its eligibility for vaccination, saying it will start offering a piercing to some gay and bisexual men who are at higher risk of exposure to monkey pox, even if confirmed case contact. Dr Mary Ramsay, head of vaccination at UKHSA, said she hoped the move would help control the epidemic. “Our extensive contact detection work has helped curb the spread of monkey pox virus, but we continue to see a significant proportion of cases of homosexuals, bisexuals and other men having sex with men. “By expanding the supply of vaccines to those at higher risk, we hope to break the transmission chains and help curb the epidemic.” The United Kingdom has secured thousands of doses of smallpox vaccine, a vaccine that also offers protection against smallpox. Initially, the vaccine was only offered for pre-exposure to healthcare workers and in high-risk contacts – ideally given to the latter within four days of exposure, although in some cases it may be given up to 14 days later. However, the Guardian has reported in the past that some case contacts have encountered difficulties and delays in accessing the vaccine. Experts have also expressed concern, with some saying the epidemic is out of control and that all men who have sex with men may need to be vaccinated to combat the spread of the virus. Among other factors, some have noted that stigma around monkey pox can make it difficult to track contacts, and the UKHSA has also identified challenges, such as the fact that contact information is not always available to identify those who may have been exposed. Although no details have yet been released on who is now eligible for the jab, the UKHSA said some factors will be involved in the criteria, suggesting that the vaccine may be recommended, for example, for someone who is having group sex. “Although most cases are mild, some people can get serious illness, so it is important to use the available vaccine to target groups where the spread is continuous. “The NHS will soon determine the details of how it will be delivered – so do not go for the vaccine yet,” Ramsay said.
