Pfizer defends COVID-19 vaccine effectiveness after Trump remarks

In a post on Truth Social, Trump asserted that he has seen "extraordinary" data from companies such as Pfizer, but criticized them for withholding results from the public and the Centers for Disease Control and Prevention. Pfizer's announcement comes after major upheaval at the CDC last week, as director Susan Monarez was fired after resisting changes to vaccine policy that were advanced by Health Secretary Robert F. Kennedy Jr, who was handpicked by Trump earlier this year.
