Mixed-dose woes: Due to their mixed immunizations, several Canadians are unable to work in other countries.

A mixed COVID-19 vaccine two doses with separate vaccines could cause more problems than just a hiccup in your vacation preparations. It could jeopardize your chances of working in another country.

Several countries do not consider those who have had mixed vaccination doses to be completely immunized. In the United States, the Centers for Disease Control and Prevention (CDC) currently does not recommend mixing COVID-19 vaccinations.

Canadians do not need to show proof of immunization to fly to the United States. Many cruise lines departing from the country, however, have vaccine restrictions based on CDC guidelines. As a result of their mixed immunizations, some Canadian cruise ship workers claim they were denied employment because they weren't considered properly vaccinated.

"It was heartbreaking," Toronto dancer Rosie Harbans, who performs in cruise ship musicals, said. "This is how I earn a living. This is how I conduct myself. This is my source of income."

After the pandemic compelled the cruise industry to shut down in March 2020, Harbans' cruise ship contract was cut short last year.

So she was overjoyed to be offered a position with a cruise company, which she will begin next month. When the cruise line learned she had mixed COVID-19 doses: one Pfizer and one Moderna, she said her happiness and her job offer evaporated.

The federal administration has stated repeatedly since mid-July that it is working with other countries to fix their differing immunisation policies. Ottawa, on the other hand, has yet to announce any progress in this area.
