Robert: Health Canada approves Omicron targeting COVID-19 booster

Health Canada has given the thumbs up to Moderna’s bivalent COVID-19 vaccine, which is designed to target the Omicron variant. This is the first COVID vaccine of its kind to achieve federal approval.
A bivalent vaccine is designed to target two different variants of the same virus. While current vaccines have proven effective against early versions of the SARS-CoV-2 virus, overall effectiveness has waned as the virus evolved and mutated.
Moderna says trial data shows when given as a fourth dose, this variant-adapted shot raised virus-neutralizing antibodies by eight-fold against Omicron.
