Canada is experiencing a resurgence of measles, with over 1,383 cases reported in Ontario this week, driven by declining vaccine confidence post-COVID and misinformation linking the vaccine to autism. Immunization coverage among children has dropped significantly, with only 70% fully vaccinated against measles, contributing to the outbreak that began after a gathering in New Brunswick last October. Health officials urge vaccinations, as the majority of hospitalized cases involve unvaccinated individuals, highlighting the need for complex interventions to address growing vaccine hesitancy.
