New Omicron booster side effects expected to be similar to previous COVID-19 shots

“The typical side effects following a vaccination can be expected,” agreed Dr. Jose Mayorga, executive director of  UCI Health Family Health Centers. “These include fatigue, sore arm, fever, and headache. The patients we have vaccinated in our clinic have had mild side effects that over-the-counter Tylenol or Motrin has relieved.” “The only side effect I got from this vaccination was peace of mind,” Mayorga told Healthline. “I feel safer against serious disease.”
