Vaccination and Immunization

Vaccines protect the body from diseases that can make you very ill. They help the body to boost its immunological defences to prevent infections without causing disease. Vaccination is a simple, effective and safe public health initiative.

COVID-19 vaccine

Vaccination of the population against COVID-19 is underway in Estrie.

Vaccination for Children

Vaccination remains the most effective public health initiative, and its safe use makes it even today one of the best preventive measures. By vaccinating your child, you are giving him one of the best protections against serious diseases. It is very important that you comply with the immunization schedule recommended by the Ministère de la Santé et des Services sociaux (MSSS) and not exceed the deadlines in order to protect your child from infections as early as possible.

There are few reasons to prevent your child from being vaccinated. If you have any questions, please speak to your family physician or to the nurse at your CLSC.

At your child's 18-month immunization appointment, the nurse will assess your child's development and health using the 18-month+ ABCdaire. She will also answer any questions you may have.

Flu vaccine

The flu spreads easily. Flu (influenza) spreads easily. Getting vaccinated every year is the best way to protect yourself from the flu and its complications.
