Covid-19 vaccines may cause mild side effects, experts say, stressing need for education, not alarm
While the world awaits the results of large clinical trials of Covid-19 vaccines, experts say the data so far suggest one important possibility: The vaccines may carry a bit of a kick.
In vaccine parlance, they appear to be “reactogenic,” meaning they have induced short-term discomfort in a percentage of the people who have received them in clinical trials. This kind of discomfort includes headache, sore arms, fatigue, chills, and fever.
