Some people who received a COVID-19 vaccine were at higher risk of stroke but an analysis found that the risk was connected to influenza vaccination, U.S. Food and Drug Administration (FDA) researchers said in a new study. The researchers, analyzing data from Medicare, detected an elevated stroke risk among the elderly following receipt of a bivalent COVID-19 vaccine made by Pfizer and Moderna and available from the fall of 2022 to the fall of 2023. There was an elevated risk of nonhemorrhagic stroke or transient ischemic attack in people 85 or older following Pfizer vaccination and people aged 65 to 74 following Moderna vaccination, the researchers found. But the researchers then looked at which people received an influenza shot at the same time as a COVID-19 shot and saw that the elevated risk only persisted among people who received the vaccines concomitantly. “This finding suggests that the observed association between vaccination and stroke in the concomitant subgroup was likely d...

Because the COVID-19 vaccines load the body with the genetic code for the thrombogenic and lethal spike protein, those who take a vaccine are vulnerable to a catastrophe if they get infected with SARS-CoV-2 after having recently taken one of the shots. Nahab et. al  from Emory University analyzed a statewide database of COVID-19 vaccine recipients. Approximately 5 million adult Georgians received at least one COVID-19 vaccine between December 2020 and March 2022: 54 percent received BNT162b2 (Pfizer), 41 percent received mRNA-1273 (Moderna), and 5 percent received Ad26.COV2.S (Johnson & Johnson). Those with concurrent COVID-19 infection within 21 days postvaccination had an increased risk of ischemic (OR = 8.00, 95 percent CI: 4.18, 15.31) and hemorrhagic stroke (OR = 5.23, 95 percent CI: 1.11, 24.64). Update: COVID-19, Flu Vaccines Taken Together Linked to Stroke Risk This analysis shows one of many great dangers present in rapid vaccine development and rollout without suffici...

A growing number of studies indicate people are at higher risk of stroke if they receive COVID-19 and influenza vaccines at the same time, though other papers have not found an elevated risk. Researchers with the U.S. Food and Drug Administration (FDA)  said  they identified an increased risk of stroke for some elderly people who received the Moderna or Pfizer vaccines concomitantly with a high-dose/adjuvanted influenza vaccine. An increased risk for people under 65 was found for people who received the Pfizer-BioNTech COVID-19 vaccine and a flu shot on the same day, researchers with Kaiser Permanente  reported  soon after. Safety monitoring by the FDA and the U.S. Centers for Disease Control and Prevention (CDC)  previously found  a safety signal for Pfizer's bivalent vaccine and ischemic stroke, a type of stroke caused by blood clotting, authorities said in January.
