MONTREAL (Reuters) – Police in the Canadian province of Quebec are searching for a man they suspect of punching a nurse in the face for giving his wife a COVID-19 vaccine without his consent, a police spokesman said on Wednesday.

Martin Carrier, a police spokesperson, said that the man approached the nurse Monday morning at the Sherbrooke pharmacy, which is located about 155 km (96 miles) southwest of Montreal. He was supposed to be administering vaccines.

Carrier reported that “our suspect immediately entered the office and began shouting at her.”

Carrier said that the man seemed shocked to learn his wife had been vaccinated by the pharmacy without his permission and he hit the nurse on the head.

Globally, nurses have suffered abuses and burnedout as a result of their work in fighting COVID-19.

Carrier reported that the suspect was either against vaccinations or his wife had actually been inoculated by the same pharmacist.

As the week approached, protests against vaccinations rose across Canada. The province of British Columbia had to shut down its schools due to anti-vaccine demonstrations.

On the campaign trail, protesters targeted hospitals and health workers. Prime Minister Justin Trudeau was furious and has promised to take action against such acts.
