If you have already had COVID-19, it is recommended by the Quebec immunization committee to receive only one dose of the COVID-19 vaccine. Current data shows that after one dose, a person who has had COVID-19 produces as many or even more antibodies than someone who has received two doses without having had the disease. Therefore, you will not be penalized for only having one dose, as a complete vaccination in your case includes only one dose. As for travel requirements and proof of vaccination, there is currently no information available. However, you can access your laboratory test results, including a positive COVID-19 test, on your online health record. This could be used as a form of confirmation if needed in the future.
