Top CDC Official Admits Covid Booster Shots May Cause More Serious Side Effects
A top CDC health official questions whether Pfizer’s Covid-19 booster shot will lead to a higher prevalence of serious adverse reactions.
During a press call Tuesday, CDC deputy director Jay Butler responded to a journalist’s question asking about potential safety concerns over a third Pfizer dose.
“We’re keenly interested in knowing whether or not a third dose may be associated with any higher risk of adverse reactions, particularly some of those more severe although very rare side effects,” Butler responded.
According to Fox News, Butler also “reiterated data suggesting local reactions and rare side effects occur more frequently after the second dose in two-dose regimens.”
On Monday, Pfizer execs held a virtual meeting with US health agencies presenting data on the efficacy of their third Covid shot, which has not yet been recommended by the CDC, and has yet to receive emergency authorization approval from the FDA.
The meeting comes as the FDA on Monday added an advisory to Johnson & Johnson’s Covid vaccine to include a warning about the possible side effect Guillain-Barré, a disorder characterized by the body’s immune system attacking itself.
Pfizer’s booster jab meeting also follows an announcement by the CDC last month saying they’d received over 1,200 reports of heart inflammation following vaccination with either the Pfizer or Moderna Covid vaccines.
Meanwhile, the country of Israel is going ahead with administering a third dose of Pfizer’s vaccine for immunocompromised patients, despite a rise in myocarditis cases among vaccinated young men.
