Introduction

There are some really interesting and concerning statistics related to COVID-19 vaccine administration in Canada when we examine sex and gender. In this article I will provide a brief analysis, overview and snapshot of some of the statistical data available from the Canadian government for this. 

Note on Lack of Data Related to Gender and Race: It is important to note that Canada (and the provinces/territories) does not appear to be collecting demographic statistical information on gender-variant and Trans people who have been vaccinated. There is also no indication that any race-based statistics are being kept either. This is not consistent with best practices for data integrity in the 21st century. This also represents missed opportunities to identify groups that may be at higher risk for Adverse Health reactions from the vaccines.

• Of the 5,488 reports, 977 were considered serious (5.5 reports per 100,000 doses administered).

Adverse event following immunization reports by age and sex

• The majority of adverse event reports were among females (82.9%) where sex was known (Figure 3), up to and including May 14, 2021.
  
  
• The rate of reports for females was 43.3 per 100,000 doses administered.
  
  
• The rate of reports for males at 10.9 per 100,000 doses administered.
  
  
  • It is unclear if this is due in part to health care seeking behaviour (e.g. reporting adverse events) or biological differences between females and males.

• The rate (number of adverse events per 100,000 doses) of reported adverse events was highest among the 30-39 year age group.
