The Milwaukee Health Department on Monday threw out 34 doses of the Moderna COVID-19 vaccine that expired before they could be used, the department said in a statement Tuesday.
"The situation that led to the error was complicated by the instruction to give only Pfizer vaccine to teachers vaccinated on Monday," according to the department's statement. "Also, a number of teachers scheduled appointments on Monday without identifying themselves as teachers until arriving at the vaccination site."
Monday was the first day educators were eligible to be vaccinated.
Workers prepared more syringes with the Moderna vaccine than people who came for it at the downtown Wisconsin Center site, according to the department.
This is the first time the Health Department has had any vaccine go unused of the more than 25,000 COVID-19 vaccine doses it has administered, according to the department.
There had been 140 extra doses but Health Department staff were able to find enough people who were eligible but did not have appointments to bring the total down to the 34 that expired, according to the department.
