Toronto parents, doctors and health authorities are on the alert Monday morning as they scan the horizon for any sign of a measles. Toronto Public Health jumped in at a daycare over the weekend where there was a known measles patient present for a period of time. Parents in the west end got a call advising them to have children vaccinated if they were not already fully protected. Family doctors are hearing from concerned parents whether their vaccinations are up to date. As of Saturday, there were six confirmed cases of measles that had been reported to Toronto Public Health, including two children under age two and four adults. All are from separate families leaving a clear prospect that measles is not fully quarantined. The video below done by the New York Times discusses the roots of the vaccine skepticism that began with a now discredited 1998 report authored by Dr. Andrew Wakefield suggesting a possible link between the measles vaccine and autism.
