Canada signs deal for Pfizer booster doses

Prime Minister Justin Trudeau says Canada has reached an agreement with Pfizer for 35 million booster doses for next year, and 30 million in the year after.

He says the deal includes options to add 30 million doses in both 2022 and 2023, and an option for 60 million doses in 2024.

Booster shots are expected to be important as the virus continues to mutate, similar to how the flu shot is altered every year to be effective against the most dominant strain.

Trudeau says these boosters will be the latest version of the Pfizer vaccine based on research and testing, and they will help Canada keep the virus under control.
