People at risk
Some people have a higher risk of complications if they catch measles. In case of exposure to the measles virus, these people should contact Info-Santé 811 as soon as possible to be evaluated and receive preventive treatment if necessary. Preventive treatment consists of an injection of antibodies that must be administered within 7 days following the exposure.
People at risk of complications are:
- Babies under one year old
- People with a weakened immune system
- Pregnant people who are not adequately vaccinated against measles
People who are considered protected
The following people are considered protected against measles:
- People born before 1970
- People who have serology showing antibodies to measles
- People who have a medical certificate confirming that they had measles before January 1, 1996
- People who have written evidence of vaccination against measles
The number of doses required to consider people protected varies:
- 2 doses:
- People born after 1980
- People born between 1970 and 1979 who are interns or health care workers, travellers in countries where measles circulates or military recruits
- 1 dose:
- People born between 1970 and 1979 who are not interns or health workers, travellers in countries where measles circulates or military recruits
- Pregnant people born between 1970 and 1979 who received only 1 dose of vaccine against measles should receive Immunoglobulins following significant exposure to measles
If you are not considered protected, to receive the vaccine, you can book an appointment on the website Clic Santé or by calling 1-877-644-4545. Measles vaccination is available at local service points in many regions of Québec.
For information on vaccination status, please contact your CLSC, local point of service or call 1-877-644-4545.
Measures to be taken for exposed persons
If you are protected against measles, it is highly unlikely that you will contract the disease. As a precautionary measure, we recommend that you watch for the onset of measles symptoms until the date corresponding to your situation (see the section Places and dates of possible exposure to a case of measles).
If you are not protected against measles, it is recommended that you:
- isolate yourself at home from the 5th day following your first exposure to measles until the 14th day inclusive after your last exposure. (You are not contagious during the first 5 days following the first exposure);
For example, if you were exposed on March 4 and March 10, you should isolate from March 9 to March 24 inclusive. - get vaccinated. A vaccine or injection of antibodies against the disease may be recommended;
- watch for the onset of symptoms until the date corresponding to your situation (see the section on Places and dates of possible exposure to a case of measles).
To learn more about the symptoms of measles and what to do in the event of symptoms, visit the page Measles.
Injection of antibodies provides immediate protection if given within seven days of contact with a contagious person. It may be recommended for people at risk.
The vaccine is intended for people aged 6 months and over who are not considered protected against measles and who have been in contact with a contagious person. It can be effective in preventing the disease if given within 72 hours of contact.
For certain situations, if you are among the at-risk individuals, you may be contacted by the Direction de santé publique of your region for further details on the recommendations to follow.
To receive the vaccine, you can book an appointment on the website Clic Santé or by calling 1-877-644-4545. Measles vaccination is available at local service points in many regions of Québec.
People in contact with exposed people do not need to isolate or restrict their contacts.
