It is OK to get a flu shot and a Covid-19 vaccine on the same day, the Centers for Disease Control and Prevention says. Officials suggest getting them in different arms, or at least an inch apart if in the same arm.
“Other than maybe making your arm more sore or having two arms that are sore, there’s not a whole lot of interaction between the two of them,” says Rachel Presti, an infectious-disease physician at Washington University in St. Louis. She’s had patients get both vaccines on the same day. “We know from other vaccines that generally giving them together is fine.”
