![]() ![]() ![]() It should be noted that the Moderna booster is only half the original dose. Moderna is still accumulating final data, but since Moderna has been shown to produce a good amount of neutralizing antibodies and total antibodies, we expect the efficacy to be on par with the Pfizer results. In the Pfizer study, they found that the relative vaccine efficacy after the booster was more than 95%, which restores the original vaccine efficacy before immunity waned. The booster shots are not only safe, they are also shown to be very effective in boosting one’s immunity to COVID-19. The benefit outweighs any risks of receiving either the Pfizer or the Moderna booster dose. In addition, the CDC found that reactions from the third dose were very similar to those after the second dose, stating that there are “no unexpected patterns of adverse reactions” and they will continue to monitor the boosters’ safety. In fact, the placebo group had more serious adverse events than the booster group.

Scientists from the FDA and CDC have closely monitored data and confirmed that vaccine protection may decrease over time. What have the FDA and CDC decided about COVID-19 booster shots and why? Pereira about the latest guidance and data on booster shots. “The data showed an increase in the immune response after a booster shot.” Pereira, medical director of the Transplant Infectious Diseases Program at NewYork-Presbyterian/Columbia University Irving Medical Center and assistant clinical professor of medicine in the Division of Infectious Diseases at Columbia University Vagelos College of Physicians and Surgeons. “The CDC and FDA made their decisions based on data that showed that booster shots are safe and effective for the general adult population,” says Dr. Furthermore, a clinical trial of the Pfizer/BioNTech’s COVID-19 vaccine booster showed that it is effective in protecting against COVID-19, indicating that a booster dose may result in increased protection compared to just having the initial vaccination series. ![]() The CDC cited data from small clinical trials that showed that while vaccines continue to protect against severe disease and hospitalization, their effectiveness at preventing COVID-19 infection appears to wane over time.
