Does Alcohol Reduce COVID-19 Vaccine Effectiveness?

“Alcohol consumption has increased at home; people are stressed,” Ilhem Messaoudi, PhD, professor of molecular biology and biochemistry and director of the Center for Virus Research at the University of California, Irvine, tells Verywell. … “Having a big amount of alcohol at one time really suppresses the immune system,” Messaoudi says. … “Moderate drinking—one serving of alcohol per day for women and two servings per day for men—can reduce inflammation and enhance the immune response to vaccines.”
