Some long-haul COVID-19 patients are reporting post-jab improvements.

  • About a third of Daniel Griffin’s patients said their sense of smell improved, or they felt less wiped out. “For some of them it was short lived. But for a chunk, it actually persisted—they went ahead, got their second shot out, and are saying, wow, they really feel like there’s light at the end of the tunnel,” says Griffin, a Columbia University clinician-researcher.

Possible Reasons: Vaccination could help root out leftover virus fragments that may continue to irritate the immune system. 

Or, perhaps the vaccine jolts the immune system into a reset. But if that’s the case, the improvements would probably fade.

The Caveats: The surveys are small and can’t prove the vaccine spurred improvements.

The Bottom Line: “It doesn’t look harmful, and it may be therapeutic,” Griffin says.
