Have you had, or are you considering getting a shingles (or other) vaccine to protect your brain health? Are you 50+ and Canadian? Would you potentially like to be on a podcast? If so, please DM me. A colleague is looking for people interested in speaking about their experience.
My most enthusiastically received public talk this year was "Is dementia a vaccine-preventable condition?" and the wonderful team at the McMaster Alumni Association, @miramcmaster.bsky.social , and the McMaster Optimal Aging portal have made it available for you if you missed it. Enjoy!

Learning lots about #lung autoimmunity as a contributor to severe #asthma from Dr Manali Mukherjee from #TheFirestone. Great reminder that blood is not always the right place to sample for autoimmunity -sputum can be a much more informative marker.

Does the misinformation coming from the US influence Canadian opinions on vaccines? Probably, but we don't have any data to know for sure. I speak to @theguardian.com here.

Misinformation from the Trump administration is cited as fuelling Canadians’ concerns over childhood vaccinations

May all your PCRs give you only specific bands of the appropriate sizes. May your gel extraction and miniprep yields be high.
May your cloning always give you at least one correct colony, and your genotyping identify the mutants you are after. ✨
