Co-administration of COVID-19, Flu, and RSV Vaccines
- These vaccines can be given together, especially for high-risk patients for severe respiratory illness (including but not limited to advanced age, cardiopulmonary disease, immunocompromising conditions, and residence in a long-term care facility) or vaccination opportunities for the patient are limited.
- Offering all recommended vaccines during the patient’s visit maximizes protection. Patients should be made aware that side effects may occur, like fever and fatigue, if multiple vaccines are given together. Side effects are generally mild and short-lived.
- If vaccines are given at different visits, there is no minimum wait period between these vaccines.
- Most importantly, ensure patients receive all recommended vaccines on time for protection against these respiratory diseases this fall and winter virus season.
