| I work in a healthcare setting, school, or day care and have been exposed to someone who has measles. |
Call Toronto Public Health at 416 338-7600 to discuss the specifics of your exposure and immunization status. |
You are at higher risk of spreading the infection to vulnerable populations |
| I am pregnant and have been exposed to someone who has measles. |
Consult with your physician. Based on when you were born and your immunization records, you may already be protected. |
Your doctor will confirm your status by reviewing your immunization records and/or giving you a blood test to checked for measles immunity. |
| I was born prior to 1970. |
Anyone born after January 1, 1970 who is not vaccinated and who has never had measles infection is at risk. People born before December 31, 1969 have likely developed immunity to the virus and are considered protected. |
It is important to watch for signs and symptoms of measles (see above and fact sheet) and if you develop any symptoms, talk to your doctor. |
| I was born between 1970-1995. |
Confirm you had measles vaccine, usually given as MMR (measles, mumps, rubella). If you had one or no shots of measles vaccine, get a first (or second) shot. |
Two doses of measles vaccine provides almost 100% protection. One shot provides 85% to 90% protection. |
| I was born after 1995. |
Confirm you had 2 doses of MMR vaccine by checking your immunization records or contacting your physician. |
In Ontario, all children are required to get 2 shots: the first dose is given on or just after the first birthday and a second shot between 18 months to 6 years of age. |
