The Food and Drug Administration hasn’t found an increased risk of stroke for seniors who’ve received Pfizer’s omicron booster shot, a federal health official said Thursday.
The FDA launched an extensive review of federal data after investigators at the Centers for Disease Control and Prevention detected a possible risk of stroke for seniors who received Pfizer’s booster.
The CDC’s Vaccine Safety Datalink, which monitors serious reactions to vaccines, showed a possible risk of stroke in late November. The FDA independently looked at data from the Centers for Medicare and Medicaid Services and its Vaccine Adverse Event Reporting System.
