The editorial about the polio outbreak in Tajikistan incorrectly states that immunization rates for polio in Ontario are between 70% and 80%. 1
The most recent data from Ontario’s Immunization Record Information System shows that 83% of 7-year-old children and 94% of 17-year-old adolescents are immunized against polio. Although immunization coverage rates for 7-year-olds have been relatively stable over the last decade, the rates have improved steadily by 17 years of age.
Under the Immunization of School Pupils Act, medical officers of health are required to maintain vaccination records of all school students for designated diseases. A written vaccination record or proof of vaccination is required by law for diphtheria, tetanus, polio, measles, mumps and rubella unless there is a valid written exemption. Parents and guardians are required to provide this information to their local public health unit and to update the information as necessary. There are specific vaccines required for children attending licensed daycare centres. The “publicly funded routine immunization schedule for children beginning immunization in early infancy” is available on the website of the Ministry for Health and Long-term Care (www.health.gov.on.ca/english/public/program/immun/immunization.html).
I agree with your opinion that vaccination — on time, every time — is our best defence against polio. This province will continue to strive to achieve the highest possible rates of immunization coverage to protect our population.
