Thank you very much, Mr. Chair.
The border measures are actually put in place to evaluate the characteristics and impacts of any of the variants of concern on both domestic and international epidemiological landscapes. When those tests are done at the border, they actually help us to look at the behaviour of the virus in terms of its transmission, its clinical presentation, as well as, “Do they actually behave the same way on the vaccine efficacy side?” We continue to use these tests to make sure that we have a better idea of the science and also to make sure that we are minimizing and reducing the importation of any kind of variant of concern that may cause more transmissibility, as was seen with the omicron virus.
Dr. Tam, do you want to add anything on that?
