CBC Radio - Dr. Samir Sinha talks about low numbers among those eligible for third dose of vaccine

"I think part of the issue may be a communication issue," says Dr. Sinha, NIA Director of Health Policy Research. "We've been using the term 'that you need two doses to be fully vaccinated' and I think people may not be aware of the significant added benefit of actually why that third dose is so important and how it can really help people get the protection they need for all of us to try to get through this winter more safely."
