Vaccine surveillance

The Government of Canada, through the COVID-19 Immunity Task Force (CITF) and the Vaccine Surveillance Reference Group (VSRG), is supporting a new nation-wide study that will look at the effects of ‘mixing-and-matching’ approved COVID-19 vaccines in adults. Approximately $4.8 million is being provided for this study, which will assess the safety and effectiveness of using two different COVID-19 vaccines for the first and second dose. The project will also study the effects of increasing the interval between doses.

The Government of Canada, through its COVID-19 Immunity Task Force (CITF) and Vaccine Surveillance Reference Group (VSRG), is investing approximately $1.3 million for two Canadian research teams to further evaluate vaccine safety and effectiveness in pregnant people.

A consortium of Canadian organizations, including the Public Health Agency of Canada (PHAC), the Canadian Research Immunization Network (CIRN), the National Advisory Committee on Immunization (NACI) and the CITF, are collaborating through the Vaccine Surveillance Reference group (VSRG) to identify new studies to support comprehensive vaccine effectiveness and safety monitoring efforts across Canada.
