Given the rapidly evolving research and communications during the rollout of COVID-19 vaccines, health care workers naturally have questions and concerns. To help answer some of our hospital worker questions, the Ontario Hospital Association convened experts in the field to create this video to explain the decision to extend the interval between first and second vaccine doses from 21-28 days to 42 days.

Featuring Dr. Peter Lin, Director of Primary Care Initiatives at the Canadian Heart Research Centre and CBC Health Columnist, Dr. Caroline Quach-Thanh, Chair of the National Advisory Committee on Immunization (NACI) and moderated by Dr. Brad Wouters, Executive Vice President of Science and Research at University Health Network, the goal of this video is to help health care workers better understand the science behind the decision and what the delay means for them.
