Sleep loss is linked to changes in several immune processes. Poor sleep may weaken your defenses against a virus. It may affect how your body responds to a vaccine, increasing your risk for illness. For this reason, sleep deprivation during a global pandemic is especially risky.

Other studies have made similar findings evaluating patients’ response to vaccines for hepatiti
