Public Health Ontario Wants people to know what immunizations actually do.

PHO released a 65-page document going over a variety of programs and information they offer. In the document, PHO explains the population that was immunized against vaccine-preventable diseases. According to the report, 91 percent of the 7-year-old population in Ontario were vaccinated for Measles and Mumps. And 85 percent were vaccinated for Diphtheria, Tetanus, Polio, and Pertussis.

The report also showed that 56% of seventh-grade students were vaccinated against human papillomavirus, but 80% received a meningococcal vaccine.

Since 2011 Ontario has carried out immunizations against Mumps, Measles, and Rubella at 12 months old. Then children are immunized again between four and six.

The report shows that in 2017 there were more than 200 cases of Mumps identified in Ontario, and PHO says this highlights the importance of keeping the two-dose minimum coverage.
