Dr. Dawn Bowdish

Congratulations to @kerryhilligan.bsky.social for her Doherty Lectureship for her most excellent body of work studying tissue immunity to infections. #ASI2025 #PerthASI

Having a blast at #ASI2025 #PerthASI &very much looking forward to the Lafferty debate with this team.Topic =‘AI in Immunology: Not really a Transformative Technology, Just New Bioinformatics We All Pretend to Understand’ We are arguing for but with the double negative that’s against. #AussiesAreFun

“Have Yourself A Merriam Little Christmas”

Merriam, a career-oriented lexicographer from the city, returns to her small town for the holidays and meets Webster, a ruggedly handsome librarian, who shows her the true DEFINITION of Christmas.

Thanks so much for coming!

Excited to hear from @msmacrophage.bsky.social about aging, infection and immunity #ASI2025 #PerthASI #immunologyiscool

Excited to share my acting debut with Ontario's public broadcaster TVO (@tvodocs.bsky.social @therundowntvo.bsky.social & more). I was in an episode on fever for the TVO Kids series 'Burps, Butts, and Bones' (do they know their audience or what?). I learned about acting from the +++talented Ryan.

VIDEO: Why Canada got publicly shamed for having so many measles cases Tonight on Village Media's 'Closer Look' podcast: An immunologist at McMaster University explains this week's announcement by the Pan American Health Organization — and how we can turn things around

I loved doing thos podcast with Scott Sexsmith and Michael Friscolanti, from Village Media about Canada’s loss of measles-free status. I lime having the longer discussions to get i to the complexity in a way you can’t in most news articles.

Iris Gorfinkel: How politics, not science, is putting vulnerable patients and health care workers at risk As a family doctor, I have seen first-hand the difference masking makes. Since my clinic adopted consistent masking, staff absences from colds, flus, and COVID‑19 have plummeted. Scaled across the

Canada has lost its measles elimination status. Dawn Bowdish, professor of medicine with McMaster University, says sustained investment in public health, outreach and a national vaccine registry could help get Canada back on track.

Measles is endemic in Canada. What happens now? healthsci.mcmaster.ca/canadas-meas... @msmacrophage.bsky.social

More news → CanadaHealthwatch.ca 🍁

'National embarrassment': Canada is no longer a country that has eliminated measles Canada has been at the centre of measles outbreak this year, with 5,138 cases reported as of Oct. 25.

Today Canada lost its measles elimination status. The problem is (primarily) due to failures in our health systems, not individual decision making and fixing it is not as simple as telling people to get vaccinated (my thoughts below with more to come).

After 26 years of elimination, Canada is set to lose its international status as a measles-free country. How did the measles get to Canada and how do we move forward? @jeyantvo.bsky.social asks Nathan VanderKlippe (@theglobeandmail.com) & @msmacrophage.bsky.social (@mcmasteruniversity.bsky.social)

YouTube video by TVO Today From Elimination to Outbreak: Measles and the Fight for Public Trust | The Rundown

The family doctor crisis, underfunding of public health, misinformation, liberal exemption policies, lack of access to vaccine hesitancy clinics have all led to the resurgence of measles. Was very happy to be invited to join @jeyantvo.bsky.social at @tvotoday.bsky.social to discuss.

Canada faces a measles resurgence, risking its elimination status. How did that happen, and where did it come from? @jeyantvo.bsky.social asks Nathan VanderKlippe (@theglobeandmail.com) and @msmacrophage.bsky.social (@mcmasteruniversity.bsky.social) tonight at 8pm | Producer: Constantina Varlokostas

I read the manuscript yesterday - what a wild immunological ride. The modified mRNA causes a boost of an inflammatory immune protein called interferon which works with the patients’ immunotherapy to get the immune cells into the tumour (which usually keeps them well away) to start killing. Wild.

New paper alert! We used our fav technique, genetic suppression, to understand how FimX controls function of the T4P PilB motor ATPase in Pseudomonas aeruginosa. Great collab with the Ellison lab at U Georgia who helped with some fancy microscopy to capture pilus dynamics! doi.org/10.1371/jour...
