Alcohol Consumption and Vaccine Effectiveness

Effects of Alcohol on Immune Function

Alcohol can increase burden on the liver, which plays important roles in immune function, and may contribute to dehydration, potentially affecting overall health status during vaccination 1
The liver's role in immune function is critical, and alcohol consumption can alter this function, particularly in individuals with pre-existing liver conditions 1

Women should limit alcohol consumption to no more than one standard drink per day, and men should limit to no more than two standard drinks per day, with one standard drink equaling 12 oz beer, 5 oz wine, or 1.5 oz distilled spirits 1
Individuals with pre-existing liver conditions should be particularly cautious about alcohol consumption around vaccination, and those with a history of alcohol abuse should avoid alcohol completely during the vaccination period 1

Proper hydration with non-alcoholic beverages should be encouraged to support recovery and immune function 1

Alcohol used for skin preparation before injection does not affect vaccine effectiveness, but should be allowed to dry completely before vaccine administration to prevent potential inactivation of live vaccines 2, 3, 4
