The number of people currently vaccinated is not sufficient to prevent the spread of measles. We cannot rely on the vaccination of others to avoid catching this disease ourselves.
In Québec at least one child in ten is at risk of catching measles and passing it on to others, be it to:
- non-vaccinated children
- babies too young to be vaccinated
- pregnant women, or people with cancer who have undergone an organ transplant and cannot be vaccinated.
