URBANDALE, IA (AP) — There was a big mistake at an Iowa mass vaccination.
An Iowa hospital says it is implementing procedures to ensure it doesn’t repeat a mistake made last weekend, when more than 100 children were given the wrong dose of a COVID-19 vaccine.
MercyOne said in a statement that the children under age 12 at a mass vaccination event on Saturday in Urbandale should have received the prescribed 10-microgram dose of the Pfizer vaccine.
Instead, they received 20 micrograms, still less than the adult dosage of 30 micrograms.
