While Canadians raced to get vaccinated against COVID-19 early in the pandemic, only 15 per cent of the population had their updated shot this fall. But the virus is still spreading.
Over the past two decades, flu shots have had a 25-40% uptake rate per year (source). It’s amazing that covid boosters are so much lower than this, though if people were recently infected or vaccinated, then maybe they aren’t allowed to get vaccinated with the booster designed for the xbb station yet.
