Canadian officials say US health institutions no longer dependable for accurate information
Misinformation from the Trump administration is cited as fuelling Canadians’ concerns over childhood vaccinations

Happy New Year!
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. ✨
