What makes AstraZeneca different? Your COVID-19 vaccine questions answered
TORONTO -- The coronavirus vaccine rollout has given some hope for an end to the pandemic, but much remains unclear as new variants spread and Canada lags behind other countries in its immunization efforts.
The Pfizer-BioNTech vaccine was the first to circulate among priority groups in 2020, followed by the Moderna shot in late December. On Feb. 26, 2021, Health Canada approved a third candidate, the Oxford-AstraZeneca vaccine, for use as it continues to review two others. Whether the vaccines will mean a return to normal remains to be seen. Meanwhile, the latest federal modelling data suggests variants of the coronavirus could spark a third wave long before most of the country is vaccinated.
