FDA, CDC rebuke Pfizer's plans for third COVID-19 shot News 12 Staff Updated on: Jul 10, 2021, 2:52am The Food and Drug Administration and Centers for Disease Control and Prevention are in disagreement with Pfizer over plans for a third COVID-19 shot. Pfizer says it's ramping up efforts to develop a third dose that it hopes will better protect people from variants, citing waning immunity from its coronavirus vaccine. Pfizer says it would soon publish data about a booster and submit it to the FDA, European Medicines Agency and other regulators for emergency approval. However, the FDA and CDC came forward together with a different take. They say Americans don't need boosters yet and that it's not up to companies alone to decide when they might be needed.
