Older age has been a major contributor to excess mortality during the COVID-19 pandemic not just in Canada.Footnote4Footnote5 Figure 2 compares the weekly death counts in Canada in 2020 to the average weekly death counts from 2015 to 2019 for people less than 65 years of age and those 65 and older. In 2020, there was a noticeable increase in the number of deaths occurring in Canadians aged 65 years and older compared to the average number of deaths in the five years prior to the pandemic, especially between mid-March and mid-May and toward the end of the year. There was little variation in weekly deaths between 2020 and the prior five years for individuals younger than 65 years of age.
There you have it no change in excess mortality under 65.
In essence there was no pandemic under 65. Vaccinate over 65 leave the rest alone.
