New data from a US Centers for Disease Control and Prevention (CDC) database suggests a possible stroke risk association for the elderly or elderly group who received a second booster shot or booster shot of Pfizer/BioNTech’s COVID-19 vaccine. But the signal is weaker than the CDC had previously flagged in January, according to health officials on Thursday, January 26, 2023.

But US Food and Drug Administration or FDA officials said they had detected no link between injections and stroke in two other safety monitoring databases. The new data was presented at a meeting of outside experts who advise the FDA on vaccine policy. Earlier this month, US health officials said they had detected a possible link to ischemic stroke in people over 65 who received a second booster shot in the Vaccine Safety Datalink (VSD) database.

They said the data was highly unlikely to represent true clinical risk. Nicola Klein of the Kaitna’s health company, mentioned at the rates that appear in the database has recurred on recent weeks. But the symptoms are still an important number, which means it is probably not a goddess.

Many people who have had a previous stroke receive the flu vaccine at the same time. It is believed to be one of the reasons. FDA scientist Richard Forshee said the agency plans to study whether there is an increased risk of stroke from receiving two injections at the same time.

Both the CDC and FDA still recommend seniors receive a Covid-19 booster shot which is now being adjusted to target the Omicron variant as well as the original coronavirus. Dr. Walid Gellad, professor of medicine at the University of Pittsburgh, said the case deserved further investigation.

“Sometimes the signal is not clear,” Gellad said via email. “It makes sense to look deeper, and it doesn’t make sense to change exercise given the known benefits (getting a booster) in this age group.”
