(Washington Insider Magazine) The CDC noted that a large study of updated bivalent vaccines from Pfizer-BioNTech using the Centers for Medicare & Medicaid Services database did not reveal an increased risk of ischemic stroke.
The Centers for Disease Control (CDC) reported that a preliminary Covid-19 vaccine “safety signal” has been identified, and whether the Pfizer-BioNTech bivalent vaccine is creating an increased risk of stroke is under investigation ( CVA) ischemic in people older than 65 years.
However, through a statement, the CDC indicated that the preliminary signal has not been identified with the Moderna bivalent Covid-19 vaccine.
“Following the availability and use of the updated Covid-19 (bivalent) vaccines, CDC’s Vaccine Safety Data (VSD) link, a near real-time surveillance system, met the statistical criteria to drive additional investigation into whether there was a safety concern for the ischemic stroke vaccine in people 65 years of age or older who received the Pfizer-BioNTech bivalent COVID-19 vaccine,” the agency said in a statement Friday.
He also noted that the rapid signal response investigation in the VSD raised the question of whether people older than 65 who received the Pfizer-BioNTech bivalent Covid-19 vaccine were more likely to have an ischemic stroke 21 days later. to vaccination compared with days 22 to 44 post-dose.
Updated Bivalent Vaccine
The CDC noted that a large study of updated bivalent vaccines from Pfizer-BioNTech using the Centers for Medicare & Medicaid Services database did not reveal an increased risk of ischemic stroke.
The health agency noted that the Vaccine Adverse Event Reporting System (VAERS), administered by the CDC and the Food and Drug Administration (FDA) have not seen an increase in reports of ischemic strokes after the update of the bivalent vaccine.
For its part, a Pzifer spokesperson, in statements to Fox News, clarified that neither Pfizer nor BioNTech, nor the CDC, nor the FDA, have observed similar findings in many other monitoring systems in the United States and around the world, stressing that there is no evidence to conclude that ischemic stroke is associated with the use of Covid-19 vaccines.
“Compared to published incidence rates of ischemic stroke in this older population, to date companies have observed fewer reported ischemic strokes after vaccination with the adapted Omicron BA.4/BA.5 bivalent vaccine. . The CDC continues to recommend vaccination with the Pfizer-BioNTech Omicron BA.4/BA.5 adapted bivalent Covid-19 vaccine for all ages and licensed indications,” the spokesperson added.
Meanwhile, Fox News medical contributor Dr. Marc Siegal stressed that this is not “proof” of a link between a vaccine and stroke.
“This is not a test. It’s that they see that there may be a link here, and they want to look into it, and they’re trying to be transparent,” Siegel said.
