The Pfizer's Covid-Vaccine Booster is rejected. This is why.
Dr. Michael Kurilla, an infectious disease specialist, said he suspected Pfizer went too far in extrapolating data on older people to a younger population.
He noted that Pfizer's studies relied heavily on measurements of antibodies, without looking at other important aspects of immune response
Philip Krause, deputy director of the FDA's, noted that Pfizer was using data that had not been reviewed by experts.
Immunologists point out that long-lasting protection comes from immune cells called B-cells and T-cells, and Pfizer only presented data on antibody response.
