Guest: Megan Ogilvie, health reporter  A global surge in measles has made its way to Canada, where there’s been almost twice as many cases just three months into this year than in all of 2023. Just in Ontario, as of Wednesday, public health officials have confirmed eight measles cases. Last year, there were seven cases in total for the entire year. Cases have now also been confirmed in Quebec, Saskatchewan and British Columbia. What does this mean for us and what do we need to know about measles vaccines? The Star's health reporter Megan Ogilvie answers some of these questions.  Audio Sources: Global News This episode was produced by Saba Eitizaz and Paulo Marques.
