Canada has just approved an updated COVID-19 vaccine to target the first highly contagious omicron variant, with doses expected to start rolling out within days. Less than half of Canadians have received a booster, while only about 12% have received a fourth dose. "As we start to head into the fall and we start to see almost certainly cases rise again, the updated booster is definitely going to be better than not getting a booster at all," said University of Arizona professor of immunobiology Deepta Bhattacharya.
