Why get vaccinated?

Vaccines stimulate our defense cells to produce substances called antibodies in what is an entirely natural protective reaction. These antibodies protect a vaccinated individual against diseases.

Vaccinations are your best protection against many serious illnesses. Do not hesitate to get yours and make sure your children and relatives are vaccinated. Basic vaccines for children are offered free of charge at your CLSC. Contact your CSSS for details on who qualifies for what type of vaccine and how to go about getting an appointment. 

Health booklet

The parent or adult who accompanies a child on the first visit for a vaccination receives a health booklet from the person who administers the vaccine. All vaccines and booster shots are recorded in this booklet. Consult the "Child vaccination" page on the Services Québec website for more information.
