PEI’s Chief Public Health Office is reporting an increasing demand for the measles vaccine. While there have been no cases of the disease on the Island for the past 12 years, the office is encouraging people to get vaccinated — especially if they plan to travel. Chief Public Health Officer Dr. Heather Morrison says the vaccine is 98 per cent effective — and the shot for measles, mumps and rubella is free. According to the federal Health Department, a total of 615 confirmed and probable measles cases have been reported by Alberta, British Columbia, Manitoba, Ontario, Quebec and Saskatchewan as of March 22nd.
