Why You Might Want to Drink Water Before You Get Your COVID-19 Vaccine or Booster Shot [Health]

Health magazine reports on why you might want to drink water before getting a COVID-19 vaccine or booster shot. The article quotes Thomas Russo, professor and chief of infectious disease at the Jacobs School. "It makes sense that you'd want to be well hydrated if you developed symptoms like a fever," he says, adding that dehydration can also "exacerbate a headache." Still, Russo stresses that "there is no data to support that this will help with the COVID-19 vaccine." Still, Dr. Russo says drinking a good amount of water before your vaccine "can't hurt"—so there's really no reason not to down a glass before your shot, just in case.
