Two nurses who gave 77 Iowa prison inmates COVID-19 vaccine overdoses have been fired.
The Iowa Department of Corrections said the incorrect doses were given to inmates at the maximum security prison in Fort Madison in April.
Authorities said at the time the inmates were given up to six times the proper dose of the Pfizer vaccine. State officials have not said how the overdoses occurred.
The nurses names were not released. A spokesman for the corrections department said Monday the inmates have been monitored and all are in good health.
