Cold & flu season is ramping up so it's a good time to revisit this review we wrote which argues that that COVID vaccination should be as comprehensive as flu vaccination and has benefits that extend beyond reducing acute infections.

Happy #FluorescenceFriday. Embryonic myeloid cells are curious. They emerge early during development and disperse throughout an embryo. During this journey, they interact with different cell populations. This myeloid cell 🔴 is seemingly probing ectoderm cells 🔵 to the point of warping their nuclei.

Prevention is cheaper & easier than treatment for lung health. My colleague Jessica Buckley (Lung Health Foundation) and I wrote this for @hilltimes.com because chronic lung disease takes decades to manifest and Canada is far behind our comparator countries in smoking/vaping prevention. #pulmsky 🫁

More doctors won’t save us if we keep creating new patients
A sustainable health-care system must pair workforce reform with prevention, and nowhere is the prevention gap more obvious than with smoking and vaping.

I'm lucky that I remember when people are nice to me and forget when people wrong me, so I had totally forgotten this brutal criticism of my last CIHR grant on studying the immunology of COVID-19 infections & vaccinations. The reviewer didn't seem to think I was qualified to lead it. Implicit bias?
