The 780,000 reports were received shortly after the COVID-19 vaccines were rolled out, and show people experienced a wide range of post-vaccination problems, including heart inflammation, miscarriages, and seizures.

"Loss of consciousness and seizure immediately following injection. Went to ER by ambulance," one person reported.

"Diagnosed with Bells Palsy today due to left-sided facial numbness and paralysis," another said.

People lodged the reports with V-safe, a text-message system created by the CDC to monitor for possible side effects of COVID-19 vaccines.

The CDC, for years, declined to make the V-safe data public, instead publishing studies that described the reports as providing reassurance about the safety of the shots. However, according to data released in 2022, nearly 8 percent of the 10 million users required medical attention or hospital care after vaccination, and many others reported missing school, work, or other normal activities.

That topline data came from check-the-box surveys.

The same judge who ordered the release of that data ordered the agency in January to disclose free-text entries from a different section where individuals could describe their experiences. U.S. District Judge Matthew Kacsmaryk, appointed by former President Donald Trump, dismissed the government's arguments that processing the responses and redacting sensitive information would require too much work.
