Did the mpox vaccine work in New York City? A new report looks for answers.

When mpox cases emerged, health officials in New York City rolled out the JYNNEOS vaccine to try to stop the spread. A new surveillance report has been compiled to see how well that effort worked. The report aimed to measure the vaccine's effectiveness in preventing diagnosed mpox infections among people in the city. However, the specific results—like how much the vaccine reduced the risk of infection—are not reported in the available summary. This type of report is observational, meaning it looks at what happened in the community rather than testing the vaccine in a controlled trial. While it's a crucial step in understanding real-world protection, the lack of reported numbers means we don't yet have a clear picture of the vaccine's performance from this particular analysis. The report serves as a checkpoint, highlighting that the work to measure protection is ongoing, and the community is still waiting for the definitive data on how well the shots worked.
