62 patients at the Riverfront Hy-Vee location in Mankato misdiagnosed COVID-19 vaccinations

Hy-Vee says 62 patients recently misdiagnosed COVID-19 vaccines due to staff oversight, the store said Friday.

The error occurred at the Mankato Riverfront location. Two staff members at the pharmacy use vaccines mixed with a sterile water injection diluent – commonly used to dilute injections – instead of the saline solution provided by Pfizer.
