Scientists Describe Rare Syndrome Following Covid Vaccinations

The Covid-19 vaccines were powerfully protective, preventing millions of deaths. But in a small number of people, the shots may have led to a constellation of side effects that includes fatigue, exercise intolerance, brain fog, tinnitus, and dizziness, together referred to as “post-vaccination syndrome.” E. John Wherry, PhD, chair of Systems Pharmacology and Translational Therapeutics, suggested caution in interpreting that result. For example, it’s possible that some of the protein may result from undetected coronavirus infections. “I would like to see more data on this topic,” he said.
