Health Canada Approves Pfizer's Covid-19 Vaccine For Use As Booster

Health Canada has approved a booster of Pfizer-BioNTech's COVID-19 vaccine for people 18 years of age and older.

The booster is intended to help people who've had their first two COVID-19 vaccine doses to maintain their protection against the virus over time.

The booster is identical to the regular Pfizer-BioNTech vaccine and is to be administered at least six months after the second vaccine dose.
