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.

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.

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.

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).

'National embarrassment': Canada is no longer a country that has eliminated measles

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.

I spoke to the CBC this week about the effects of having universal COVID vaccines in some provinces but for pay in others. "... all serious infections tend to have a bigger impact for people who can least afford to pay." See our review for data to back up that statement tinyurl.com/3tx7fc3z

Albertans deemed to be at high risk from COVID-19 are now eligible to be immunized, with the first phase of the government's controversial new vaccine rollout going into effect on Wednesday.
