A review of adverse events following vaccination against COVID-19 with mRNA vaccines in the U.S. confirms that most side effects were mild and decreased substantially after one day. The new study, published in The Lancet Infectious Diseases journal, suggests that for more than 298 million vaccine doses administered between December 2020 and June 2021, 92% (313,499/340,522) of reported adverse events were not serious, and less than 1% of v-safe participants reported seeking any medical care following vaccination.
