Nearly all cases are reported in Europe and the Americas among men who have sex with men, according to WHO.
"We have known from the beginning that this vaccine would not be a silver bullet, that it would not meet all the expectations that are being put on it, and that we don't have firm efficacy data or effectiveness data in this context," Lewis told reporters.
"People do need to wait until the vaccine can generate a maximum immune response, but we don't yet know what the effectiveness will be overall," Lewis said. A small study from the 1980s found that the smallpox vaccines available at the time were 85% effective at preventing monkeypox. Jynneos was approved in the U.S. in 2019 to treat both smallpox and monkeypox, which are in the same virus family.
The WHO has observed some mutations in the monkeypox virus though it's not year clear what these changes mean for the behavior of the pathogen and how it impacts the human immune response, Lewis said. A pet becoming infected is not unusual or unexpected, said Dr. Mike Ryan, head of the WHO's emergencies program. Dr. Sylvie Briand, head of pandemic preparedness at WHO, said this does not mean that dogs can transmit the virus to people.
