A U.S. senator is questioning why a top agency was expecting hundreds of safety signals for the COVID-19 vaccines.

Dr. Rochelle Walensky, director of the U.S. Centers for Disease Control and Prevention (CDC), claimed in 2022 that safety monitoring revealed no “unexpected safety signals” for the vaccines.
