“That’s a reasonable thing to do,” he said.

Schaffner said people who are worried could consider getting each shot at different times rather than together. “That’s a hard equation for the average person to do,” Schaffner said. William Schaffner, an infectious disease expert at Vanderbilt University. “The risk of serious disease associated with both influenza and Covid for the population at highest risk, which is of course, older persons, is so much greater than the potential increased risk associated with a vaccine,” said Dr. Researchers say they are continuing to probe the possible link, but in the meantime, they say everyone should still get vaccinated since any tiny increase in risk of a stroke after vaccination is dwarfed by the increased risk of stroke or other serious outcomes following either a flu or Covid-19 infection. Tom Shimabukuro, director of the Immunization Safety Office at the CDC in a public presentation of the data on Wednesday to the CDC’s Advisory Committee on Immunization Practices. “Available data do not provide clear and consistent evidence of a safety problem for ischemic stroke with bivalent mRNA Covid-19 vaccines when given alone or given simultaneously with influenza vaccines,” said Dr. “I mean it is trivial in comparison to the risk for people over 85 of dying from Covid.”Īt least five other recent studies - many launched to try to tease out this link, have not found any additional risk of stroke after vaccination for Covid-19, influenza or both. Steve Nissen, a cardiologist and researcher at the Cleveland Clinic in Ohio. “The absolute risk is miniscule,” said Dr. In additional analysis of the Medicare claims data, the FDA researchers found a very slightly increased risk of stroke in adults ages 65 and older who’d only gotten a high dose flu shot. In absolute terms, the extra risk from high-dose flu shots amounted to 1-2 strokes for every 100,000 doses.

That said, the risk identified in the FDA’s study appears to be very small - roughly 3 strokes or transient ischemic attacks for every 100,000 doses given - and the study found it may be primarily driven by the high-dose or adjuvanted flu vaccines, which are specially designed to rev up the immune system so it mounts a stronger response to the shot. It is the second study to find an elevated risk of stroke for seniors after Covid-19 and flu vaccinations given together. The US Centers for Disease Control and FDA issued a public communication in January explaining that one of their near real-time vaccine safety monitoring studies - called the Vaccine Safety Datalink - had picked up a small and uncertain risk of stroke for older adults who received a dose of Pfizer’s bivalent Covid-19 vaccine and a high-dose or adjuvanted flu shot on the same day. That study triggered the FDA’s broader look at strokes after vaccination noted in the medical records of seniors on Medicare. The safety signal was detected by experts at the US Food and Drug Administration who analyzed data from Medicare claims. Vaccines for Covid-19 and influenza may slightly increase the risk of strokes caused by blood clots in the brains of seniors, particularly when the two vaccines are given at the same time and when they are given to adults who are age 85 and older, according to a new study.
