A new study analyzing data from the CDC’s V-safe surveillance system has identified 185,285 people who reported that their health remained worse three months or longer after COVID-19 vaccination and who attributed that deterioration to the vaccine.
The findings come from an analysis by MIT researchers Retsef Levi and Nelson Lu of one of the largest active COVID-19 vaccine surveillance datasets ever assembled.
V-safe enrolled more than 10 million COVID-19 vaccine recipients and repeatedly contacted participants after vaccination to ask about symptoms, daily functioning, healthcare utilization, and changes in their health. Unlike VAERS, which relies primarily on spontaneous adverse-event reports, V-safe actively prompted enrolled vaccine recipients to provide follow-up information over time, including at 3, 6, and 12 months.
Among 9,904,924 V-safe enrollees aged 16 or older included in the analysis, 185,285 (1.87%) reported prolonged worsening of their health that they believed was related to COVID-19 vaccination. Women reported the problem at an even higher rate: 137,430 of 6,141,800 women, or 2.24%.
