We've been hearing a lot about vaccinations recently, as health officials battle a disturbing rise in cases of measles and other diseases. These conversations usually centre on reminding parents why it's so important to have their children vaccinated — but what about adults? Grown-ups need vaccinations too, and data from the Public Health Agency of Canada suggests that most of us think we're up to date with our shots — but we're not. This week on The Dose, host Dr. Brian Goldman talks to family physician and researcher Dr. Iris Gorfinkel for a primer on what vaccines we need as adults, when we need them and why we're falling behind in keeping up with potentially lifesaving immunizations.
