  • Influenza
  • Live Attenuated Influenza Vaccine (LAIV) Issues

One of our young patients made it impossible to administer the second part of the FluMist dose. What should we do?

A half dose of FluMist (or any other vaccine) is a non-standard dose and should not be counted. If you were unable to give the second half of the vaccine at that same appointment, you will have to provide another full dose of influenza vaccine at another time. If you want to give FluMist again, you should wait four weeks, because it is a live vaccine. Alternatively, you can give inactivated influenza vaccine any time after this partial dose.
