The nurse who performed the vaccination has since been fired and an investigation is underway.

One of the mothers speaking to a news reporter about the incident

The shocking blunder was first reported by the media and officially confirmed on Sunday by local authorities in the Sorocaba municipality of Brazil’s Sao Paulo state.

Shortly after returning home, the babies developed a high fever and were given medicine which failed to improve their condition.

The two mothers, Ana Cláudia Viello and Kethilyn Monteiro Da Silva were then contacted by Sorocaba’s health secretary, Vinicius Rodrigues, who informed them that a mistake had been made and the children were injected with the Pfizer COVID-19 vaccine.

Ana Cláudia Viello said:

“I know everyone makes mistakes, but a mistake like that is unacceptable. I don’t want to punish the nurse, but I want this incident to serve as a warning to other medics and other moms: tell them to double-check what they’re giving to your kids.”

The babies are placed in the local Gpaci hospital and won’t be able to return home for some time. The local authorities contacted Pfizer and were told that the children should be monitored for the next 10 to 15 days.

The girl and the boy are now being tested every 48 hours, with blood samples taken from them and ultrasound and ECG exams performed.
