According to guidance from the Centers for Disease Control and Prevention (CDC), patients can receive a COVID-19 and influenza vaccine at the same time. If co-administered, COVID-19 vaccines and influenza vaccines that may be more likely to cause a local reaction should be administered in different limbs, if possible. Influenza vaccination should be deferred for patients with suspected or confirmed COVID-19, regardless of whether they are asymptomatic, until they have met the criteria to discontinue isolation.

Patients with COVID-19 may take longer to develop symptoms than those with influenza. Although the time between infection and symptom development may be as little as 1 day for both conditions, patients with influenza typically become symptomatic within 1-4 days, whereas those with COVID-19 may take as long as 14 days to become symptomatic. Both COVID-19 and influenza can be spread at least 1 day prior to symptom development.
