34 doses of Moderna COVID-19 vaccine expired before it could be used

MILWAUKEE - The Milwaukee Health Department says 34 doses of Moderna COVID-19 vaccine expired before they could be used on Monday, March 1. 

Officials say more syringes had been prepared with the vaccine than individuals presented themselves for Moderna vaccination at the Wisconsin Center. This is the first time any vaccine has expired and gone unused by the Health Department.

A news release says the situation that led to the error was complicated by the instruction to give only Pfizer vaccine to teachers vaccinated on Monday. Also, a number of teachers scheduled appointments on Monday without identifying themselves as teachers until arriving at the vaccination site.

In the hours leading up to the vaccine expiration, officials say the Health Department team rushed to identify unscheduled, eligible vaccination candidates. Officials say that effort reduced the potential waste from 140 vaccine doses to the 34 that did expire.

This incident is the subject of ongoing review by the Milwaukee Health Department. It is clear at this stage that no intentional or malicious action was involved in the incident.
