Ontario, Canada's 5-year-old universal flu vaccination plan is about to be researched for its efficacy at the behest of the Ontario Ministry of Health.

The Public Health Agency of Canada is expected to issue a call soon for proposals to study Ontario's flu shot program. Meanwhile, the Canadian government has bought 900,000 additional doses of the vaccine to meet an increased demand for the shots, believed caused in part by publicity about U.S. vaccine shortages.
