Health Canada has approved Pfizer’s new bivalent COVID-19 vaccine, which targets the virus strains now most common in Canada.

The updated version of the Pfizer-BioNTech Comirnaty COVID-19 vaccine targets the Omicron BA.4 and BA.5 subvariants, as well as the original strain of the virus, and is authorized for use as a booster dose in people 12 years of age and older.

“The booster is expected to trigger a strong immune response against both the original SARS-CoV-2 strain as well as the Omicron BA.4/BA.5 subvariants,” Health Canada said in a media statement.

“It is expected to have a similar safety profile to the original Pfizer-BioNTech Comirnaty vaccine, with mostly mild side effects.”
