A 2022 research review looked into the connections between the vaccine and the risks of getting long COVID. Researchers found low level evidence that those who received at least one dose of the COVID vaccination may be at a reduced risk of long COVID. Some evidence suggested getting more than one dose further reduced the risk.
But some studies found no change in long COVID risks or even worsening of symptoms after vaccination. Until more research is available, it’s tough to truly know the potential connections between long COVID and vaccination.
