• Influenza
  • Live Attenuated Influenza Vaccine (LAIV) Issues

Can FluMist be administered to people with minor acute illnesses, such as a mild upper respiratory infection (URI) with or without fever?

Yes, unless clinical judgment suggests nasal congestion is present that might keep the vaccine from making good contact with the nasopharyngeal mucosa. In that case, consider either deferring its use until the congestion resolves or using an appropriate alternative influenza vaccine, if available.
