Immune Sub-Study

Study Purpose

The Immune Sub-Study was developed as a sub-protocol of the Canadian COVID-19 Vaccine Registry for Pregnant and Lactating Individuals (COVERED). The larger vaccine study aims to assess safety, effectiveness, and acceptability of COVID-19 vaccination in pregnant individuals. The Immune Sub-Study aims to enable a better understanding of the immune response of the COVID-19 vaccine generated during pregnancy by looking at maternal and infant blood samples, as well as breast milk.

Initial engagement has been established at BC Women’s Hospital with the potential for additional sites throughout BC.
