Getting Pfizer’s Covid bivalent booster and a flu shot on the same day may raise the risk of a stroke, a small official analysis suggests.
The Food and Drug Administration (FDA) found the preliminary link while scouring vaccine injury databases after a separate safety concern was raised about Pfizer’s jab.
Following the availability and use of the updated (bivalent) COVID-19 vaccines, CDC’s Vaccine Safety Datalink (VSD), a near real-time surveillance system, met the statistical criteria to prompt additional investigation into whether there was a safety concern for ischemic stroke in people ages 65 and older who received the Pfizer-BioNTech COVID-19 Vaccine, Bivalent. Rapid-response investigation of the signal in the VSD raised a question of whether people 65 and older who have received the Pfizer-BioNTech COVID-19 Vaccine, Bivalent were more likely to have an ischemic stroke in the 21 days following vaccination compared with days 22-44 following vaccination.
The Centers for Disease Control and Prevention (CDC) says that a preliminary COVID-19 vaccine “safety signal” has been identified and is investigating whether the Bivalent Pfizer-BioNTech vaccine creates an increased risk of ischemic stroke in people 65 and older.
In the Friday statement, the CDC said that the preliminary signal hasn’t been identified with the Bivalent Moderna COVID-19 vaccine.
Moderna and the Food and Drug Association (FDA) have been accused of concealing data during the approval process for the pharma giant’s bivalent Covid booster.
Vaccine advisors who signed off on the updated shot late last year claim they were not shown trial data that indicated the booster was actually less effective at preventing Covid than the older vaccine it was meant to replace.
While the early trial results had substantial limitations, ‘disappointed’ and ‘angry advisors say its omission from panel discussions shows a remarkable lack of transparency.
