“Did these vaccine mandates work in light of omicron? The answer is we don’t know, and we wouldn’t be able to know because we don’t have a randomized controlled trial,” said Ankur Pandya, associate professor of health decision science. Did they work? (Washington Post)Įxperts say it’s not clear if vaccine mandates to enter restaurants and public places have helped to slow the spread of COVID-19, because the mandates were only in effect for a couple of months in most cities and it can be difficult to show where people may have been infected. March 3: Cities are ditching vaccine mandates to dine out and watch shows. William Hanage, associate professor of epidemiology, noted that it while it will take time to have definitive answers about the impact of vaccination on coronavirus transmission, the rapidly falling number of cases and hospitalizations suggests that vaccines are helping slow spread. So what does this mean for vaccinated individuals in the face of Omicron? (Globe and Mail) March 4: Public health restrictions in Canada are being dropped. “When I say that, I mean things like a KF94, N95, two procedural masks one layered over the other will help.” “We can help those people by giving them good quality masks,” said William Hanage, associate professor of epidemiology.

Glimcher Associate Professor of Immunology and Infectious Diseases, noted that it’s “not an enviable task.” He asked, “Do you call it over when there still might be a wave in one part of the world but it’s a small part?” And Caroline Buckee, professor of epidemiology, said that the criteria for declaring a pandemic’s end are more social and political than scientific. The World Health Organization is responsible for officially declaring the pandemic “over” at some point-but the decision is a complicated matter with political, financial, and health implications, say experts.
