With influenza (flu) season approaching, there may be compelling logistical advantages to offering patients COVID-19 and flu vaccines on the same day.  Per CDC’s clinical considerations for COVID-19 vaccines, you can safely administer COVID-19 and flu vaccines (both live, attenuated, and non-live influenza vaccines) without regard to timing. This includes administration of COVID-19 and flu vaccines on the same day and coadministration within 14 days. 

When deciding whether to coadminister vaccines, please consider:

• whether the patient is behind or at risk of becoming behind on recommended vaccines;
• the patient’s risk of vaccine-preventable disease;
• the reactogenicity profile of the vaccines; and
• the likelihood of avoiding a missed opportunity to vaccinate.

Best practices for administering multiple vaccines include the following:

• Label each syringe with the name and the dosage (amount) of the vaccine, lot number, the initials of the preparer, and the exact beyond-use time, if applicable.
• Separate injection sites by 1 inch or more, if possible.
• Administer the COVID-19 vaccines and vaccines that may be more likely to cause a local reaction (i.e., adjuvanted influenza vaccines) in different limbs, if possible.

Flu vaccination will reduce the burden of flu illnesses, hospitalizations and deaths on the health care system and help conserve healthcare resources for COVID-19 and other conditions.
