Drinking this much could make your vaccine less protective, say experts

“If you are truly a moderate drinker, then there’s no risk of having a drink around the time of your vaccine,” Ilhem Messaoudi, director of the Center for Virus Research at the University of California, Irvine, who has conducted research on the effects of alcohol on the immune response, told New York Times. “But be very cognizant of what moderate drinking really means. It’s dangerous to drink large amounts of alcohol because the effects on all biological systems, including the immune system, are pretty severe and they occur pretty quickly after you get out of that moderate zone.”
