Despite having been approved, there is still no confirmed efficacy estimate for the Jynneos vaccine against monkeypox, because previous studies had only looked at animals and measured human immune response data.
More than 66,000 cases of monkeypox have been detected worldwide.but new infections have declined since August.
The United States has administered more than 680,000 doses of the Jynneos vaccine, focusing its efforts on gay and bisexual men, as well as transgender and gender diverse people.
