The director of the Centers for Disease Control and Prevention (CDC) has acknowledged publicly for the first time that the agency gave false information about its COVID-19 vaccine safety monitoring.

… Walensky’s agency had promised in several documents, starting in early 2021, to perform a type of analysis called Proportional Reporting Ratio (PRR) on reports submitted to the Vaccine Adverse Event Reporting System, which it helps manage.

But the agency said in June that it did not perform PRRs. It also said that performing them was “outside th[e] agency’s purview.”
