As concerns mount about a large outbreak of an especially virulent form of mpox in central Africa and an uptick in U.S. cases since early last year, the mpox vaccine appears to give long-term protection, the Centers for Disease Control and Prevention reported Thursday.
In a separate report, the CDC indicated that overall new mpox infections across the U.S. have remained at a steady, low level — about 60 cases weekly, compared with 3,000 cases a week at the outbreak’s summer 2022 peak — in recent months. However, cases so far this year are elevated nationally compared with the same period in 2023 and have seen a sharp increase in New York City.
People who have gotten two doses of the Jynneos mpox vaccine are protected against infection and don’t need a booster at this time, according to the CDC.
