Can vaccinated people get long Covid? Doctors say risk is 'very, very small' [View all]

Dr. Michele Longo, an assistant professor of neurology at Tulane University in New Orleans who works with long-haul patients, said she has not seen such patients following a breakthrough infection. Neither has Dr. Maureen Lyons, medical director of the Care and Recovery from Covid-19 Clinic at Washington University in St. Louis.

Dr. Ziyad Al-Aly, a clinical epidemiologist, also at Washington University, is studying the effects of Covid-19 vaccination on the risk of long Covid-19. His research, which is not yet finished, looks at information on more than 5 million veterans within a Department of Veterans Affairs database, including 200,000 who were diagnosed with Covid-19.

"Of the people who get vaccinated and end up with a breakthrough infection, their risk of coming back to the clinic with some long Covid manifestation is very, very small," Al-Aly said.
