CDC: Vaccine found safe, effective against mpox during outbreak

In a study of men under age 50 who were eligible to receive the JYNNEOS vaccine to prevent monkeypox (mpox) during the U.S. outbreak this year, unvaccinated men were 10 times more likely to get the virus than men who received the two-dose vaccine, and seven times more likely to get it than men who received only one vaccine dose, the Centers for Disease Control and Prevention reported yesterday. A second study  found no major vaccine safety concerns after nearly 1 million JYNNEOS doses were administered in the U.S. during the outbreak, CDC said. The agency recommends the vaccine for people at risk for the virus, and encourages everyone eligible to receive the complete two-dose series for best protection.
