Jynneos mpox vaccine provided strong protection against infection, new CDC data show
People who received one or two doses of mpox vaccine contracted the infection at substantially lower rates than unvaccinated people, a study published Thursday by the Centers for Disease Control and Prevention suggested.
The analysis, published in CDC’s online journal Morbidity and Mortality Weekly Report, showed that unvaccinated people were 9.6 times more likely than fully vaccinated people to develop mpox. The incidence of infection was 7.4 times higher in unvaccinated people than in people who had received a single dose of the vaccine. The vaccinated participants had received their most recent shot at least 14 days prior to having been infected.
