Researchers found that nearly 30% of Canadian adults (nine million people) were infected during the Omicron wave early in 2022, compared with just 10% who were infected in the previous four waves. Of those infections, one million were among the country’s 2.3 million unvaccinated adult population - representing 40% of all unvaccinated adults. Despite the high numbers of infections, the study also revealed that every dose of vaccine and previous infection boosted immune responses. Canadian adults with three vaccine doses and a past infection from COVID-19 had the highest protection.
