A top coronavirus vaccine adviser to the Centers for Disease Control and Prevention (CDC) resigned from the agency, citing concerns that she would no longer be able to help the most vulnerable people following a change in the agency’s recommendations for healthy children and pregnant women.

Lakshmi Panagiotakopoulos said she could no longer help vulnerable people after officials removed recommendations to immunize children and pregnant women.

HHS Secretary Robert F. Kennedy Jr. announced that he has unilaterally struck the recommendation that healthy children and healthy pregnant people get Covid booster shots.
