Hy-Vee has confirmed that staff at one of its Minnesota stores incorrectly diluted a Pfizer COVID-19 vaccine that was then administered to 62 patients.
The grocery store chain, whose pharmacies are among three authorized in Minnesota to administer the vaccines as part of a federal program, said that the incident happened recently at its Riverfront Hy-Vee pharmacy in Mankato.
It said that there was an oversight when giving the first dose of the vaccine to 62 patients.
As it explains: "Two pharmacy staff members used vaccines mixed with a sterile water injection diluent – which is commonly used to dilute injections, rather than the saline diluent provided by Pfizer."
The chain says it has consulted with third-party doctors working on the vaccine process, and has "received confirmation that there is no reason for medical concern."
"We also have had no patients report any side effects," it added.
"As soon as we were made aware of the incident, we started personally calling the affected patients," it continued. "We have reached out to the manufacturer and are working with each of the patients on next steps. We also have reported this information to the appropriate regulatory agencies and have retrained all of our pharmacy staff members at this location. "
"We remain committed to playing an important role in administering the COVID-19 vaccine in our local communities."
