A public health unit in southwestern Ontario is apologizing to "a gentleman in Texas" who ended up answering calls from Canadians trying to book a COVID-19 vaccine appointment.

A spokeswoman for Lambton Public Health says an email news release issued on Tuesday had a wrong phone number for a local vaccine call centre.

Kelly Francis says the release asked people who are eligible for a third dose of a COVID-19 vaccine to call the centre to register.

She says the health unit was made aware on Wednesday that the calls were going to a man in Texas.

Lambton Public Health apologized to the American in a tweet on Wednesday, saying "our intent was certainly not to inundate you with our local vaccine queries."

The unit announced Tuesday it would offer a third dose to individuals with high-risk medical conditions and residents living in long-term care, high-risk retirement homes and First Nations elder care lodges.
