TriMed has added a new system rule to ensure proper spacing for live-virus vaccines, including MMR, Varicella, and live influenza (FluMist®). These vaccines may be administered on the same day; however, if given on different days, they must be separated by at least 28 days. If administered before the 28-day interval, the later dose is considered invalid. Please note: the four-day grace period does not apply to the interval between two live-virus vaccines.

Setup Required: To enable this functionality, go to Admin > Immunization > Influenza > FluMist CVX Codes and add the appropriate FluMist CVX codes.

How it Works: If a patient has received FluMist, and an MMR and/or Varicella vaccine is ordered within 28 days, the system will display a note alerting the user, as shown in the example below:
