The U.S. Centers for Disease Control and Prevention (CDC) is admitting it gave false information about COVID-19 vaccine surveillance, including inaccurately saying it conducted a certain type of analysis over one year before it actually did.

The false information was conveyed in responses to Freedom of Information Act (FOIA) requests for the results of surveillance, and after the CDC claimed COVID-19 vaccines are being monitored “by the most intense safety monitoring efforts in U.S. history.”

“CDC has revisited several FOIA requests and as a result of its review CDC is issuing corrections for the following information,” a CDC spokeswoman told The Epoch Times in an email.

No CDC employees intentionally provided false information and none of the false responses were given to avoid FOIA reporting requirements, the spokeswoman said.
