Importance of Immunization

Vaccines are used to safely help the immune system to develop a response to protect the body from disease. They are used to immunize against many diseases and illnesses that could be serious or even fatal without this protection. Vaccines are given by a schedule throughout the lifespan to ensure ongoing protection. Learn more about immunization

Immunization is necessary for two reasons:

  • to protect the individual and to protect communities. Vaccines protect an entire population by preventing the spread of disease from one individual to another;
  • the more people immunized, the less chance for disease to circulate.

The best protection comes from being vaccinated according to the Ontario schedule.   

Staying up to date with all doses of vaccines is important for each age and stage of life.

Vaccination is the best way to protect your child's health. 

Parents are responsible for the well-being of their children, including protecting them from illness caused by diseases that are vaccine-preventable. Learn about vaccination and why it is important to your child's health, A Parent's Guide to Vaccination. Learn more about individual vaccines by reading Immunization Fact Sheets.

Every year, public health nurses look at the records for students in licensed child cares, elementary and secondary schools. This is done to make sure students are up to date with vaccines in order to ensure the health of everyone attending.

Children Attending Child Care

Licenced child care operators in Ontario are responsible for keeping a record of immunization on file for all children enrolled in their care (Child Care & Early Years Act Ontario). Health Units are responsible for assessing the immunization status of children in child care centres to ensure they are up-to-date with their immunizations, or have a valid exemption. Parents are responsible for following the Publicly Funded Immunization Schedule for Ontario, maintaining a current copy of their children’s records and sharing it with their Child Care Provider. Your child care operator works with the Timiskaming Health Unit to ensure your record is regularly assessed and up-to-date.

Vaccine Requirements for School

Vaccines are a safe and effective way to keep children healthy. Diseases are easily spread among children and can cause serious illness and complications. Schools are places in which infectious diseases are commonly spread. Vaccines work by triggering a natural response in the body to fight off disease. It is important for children of this age to be up-to-date with their vaccinations.

All health units in Ontario are responsible for ensuring that children who attend school are immunized according to the Immunization of School Pupils Act.

Public health nurses review all students immunization records. If your child is missing any requirements, you will receive notification by letter. Your child could be suspended from school if their immunizations are not up-to-date, or if their immunization records are incomplete.

Let's work together to keep our children healthy and our schools disease-free.

See Immunization Information for Children at School for more information. 

Pregnant Women

It is important to talk to your health care provider to find out if you require any vaccinations during your pregnancy. For more information visit:

Vaccines and Records

Every time that you or your child receives an immunization, you should receive a record of that vaccine. Keep that information in a safe place. Your health care provider can write vaccines into the record for you, and you should keep the card with you as your personal record.

Please note: Health care professionals do not report immunization dates to the Health Unit. Parents must report the dates of their children's immunizations to the Health Unit if they attend day care or school.

Please see Immunization Records (Yellow Card) for easy access to viewing and updating your records.

Vaccine Clinics

Timiskaming Health Unit provides vaccines in a variety of settings for individuals who are eligible. See Immunization Clinics.
