Training our immune systems: Why we should insist on a high-quality COVID-19 vaccine

Our first exposure to a pathogen, either naturally or via vaccination, can affect how our immune system responds in the future to the same or similar pathogens.

Are local shutdowns effective, or should COVID-19 lockdowns be in lockstep provincewide?

With sufficient testing and co-ordination, reopening schools and businesses in areas without active outbreaks can be as effective as a wide lockdown in minimizing COVID-19 cases, according to a new model.

Canadians are less willing to fly during COVID-19 than Americans

‘Schitt’s Creek’ and ‘Letterkenny’ are love letters to rural Canada

Shows like ‘Schitt’s Creek’ and ‘Letterkenny’ upend how we imagine rural Canada to be. The small-town dynamics represented are wonderful presentations of what it means to be human.

Why vaccines are less effective in the elderly, and what it means for COVID-19

Immunosenescence — the decline of immune system function with age — means that vaccines are not as effective in older adults, the demographic most susceptible to many diseases, including COVID-19.

Trouver des toilettes publiques pendant la pandémie ne devrait pas être aussi difficile

100 days of coronavirus has sent shock waves through the food system

COVID-19 has given society a teachable moment, and we should now establish the policies, programs and technologies to ensure our food system becomes stronger, more resilient and more equitable.
The scope and length of vaccine testing experiments usually mean decade-long timelines for development. (Pixabay)

Fast COVID-19 vaccine timelines are unrealistic and put the integrity of scientists at risk

It usually takes 10 years for a new vaccine to complete clinical trials, but we’ve been promised a COVID-19 vaccine in 12 to 18 months. Even if such fast-tracked development is possible, is it wise?
