What is Measles (a.k.a. rubeola, red measles)
Highly contagious virus that spreads through contact with infected surfaces or air (up to 2 hours). It infects the respiratory tract and then spreads throughout the body.
- Being vaccinated is the best way to prevent getting sick or spreading it to other people.
- Measles has been identified in Calgary and surrounding area in March 2025.
Symptoms
🚨Stay home & call Health Link (811) before visiting a doctor if you have:
- Fever (38.3°C or higher),
- Cough, runny nose, and/or red eyes,
- Red, blotchy rash (starts behind ears & face, spreads to body, arms, & legs).
✅ Considered Immune and Not At Risk if:
- Born after 1970 and had 2 doses of MMR vaccine (no booster needed).
- Had confirmed measles infection.
- Immune mothers (2 doses MMR vaccine or prior infection) transfer some immunity to baby through the placenta (3-9 months worth!)
🚫 Considered Not Immune and At Risk if:
- Fewer than 2 doses of MMR vaccine and/or no history of infection.
🤔 Not Sure? Check your Alberta MyHealth Records, text 88111, call Health Link (811), or visit your public health office.
Measles-Mumps-Rubella Vaccine (MMR) or MMR-Var (Varicella)
- 2 doses provides nearly 100% protection against measles.
- Given at 12 & 18 months, and to those born in 1970 or later with fewer than 2 doses.
- Babies 6+ months old may be eligible for an earlier dose during outbreaks but still need 2 more doses after 12 months for full immunity. Call Health Link (811) or speak with your GP if your baby may have been exposed.
- Not recommended during pregnancy due to the theoretical risk of infection with a live component of the vaccine.
- Safe after birth, even if breastfeeding.
How to Get Vaccinated
📅 Book online, call 811, or visit a public health office or pharmacy (age 5+).
What if You are Exposed, Not Immune, & Pregnant?
📞 Call Health Link (811) right away – you may be eligible for a vaccine or immune globulin to lower the risk. Measles during pregnancy can cause prematurity and low birth weight. Pregnant, non-immune women are at increased risk of severe illness.
