With people already getting doses of the first approved COVID-19 vaccine, Canada said that people who've tested positive might not get doses while there's a limited supply.
The National Advisory Committee on Immunization (NACI) released recommendations on December 12 about the use of vaccines for COVID-19.
In the context of limited vaccine supply, initial doses may be prioritized for those who have not had previously PCR-confirmed SARS-CoV-2 infection.

It's recommended that a complete vaccine dose may be offered to people in the authorized age group who have tested positive before.
However, when there's a limited supply — as we're seeing right now — doses might be prioritized for those who haven't had a confirmed case.
Before getting the vaccine, testing to show if you've been infected isn't necessary.
Recently, Health Canada released advice about who shouldn't get the Pfizer-BioNTech vaccine.
Canada is planning on having everyone in the country vaccinated by the end of 2021.
