As part of the partnership between the CTN and CATIE, we have collaborated to put together a living document to provide the latest information on COVID-19 vaccination third doses for people living with HIV across Canada. This information, available here, will be updated as more guidance from across Canada becomes available. Below is an excerpt from the CATIE blog, written by Shari Margolese, the Community Co-lead of the CTN’s Cross Core Community Collaborative (C4) Teams.

I consider myself to be relatively well-versed in medical jargon and finding information, but I’m confused, and information is hard to come by and difficult to find…
