Mpox Outbreak Risk Remains in 2023

Precision Vaccinations

The U.S. CDC Morbidity and Mortality Weekly Report (MMWR) Podcast Briefing, published today, offers an overview of the latest scientific information regarding mpox vaccinations.

This podcast discusses three MMWR reports as of the week of May 15, 2023.

First, although the number of mpox cases has decreased since the peak of the U.S. outbreak in August 2022, the risk for future outbreaks remains.

And clinicians need to be alert for new cases, and people at risk should continue to take prevention measures.

Second, a new report looking at data from 12 U.S. jurisdictions shows Bavarian Nordic JYNNEOS® (MVA-BN) vaccine effectively prevents mpox in people at high risk for mpox.

Third, a study of mpox patients in New York provides evidence that the JYNNEOS vaccine is highly effective against mpox. 

However, the CDC and other health agencies in France, South Korea, and Spain previously reported various mpox breakthrough cases in 2023.
