The essentials
- Usual timing
- Understanding previous Men-C-C doses
- How to get it
- Ask a primary care provider or public health unit about local appointments and funding.
Men-C-C protects against meningococcal group C. It was used for Ontario’s routine 12-month dose. Families may still see this name on immunization records.
School status
Meningococcal disease is school-required, but public health needs to review the record against the requirements for the child’s age. A previous infant dose does not replace the adolescent review.
Side effects & precautions
Soreness, redness or swelling where the needle went in, fever or fussiness can occur. Side-effect guidance
A severe allergic reaction is rare. Any previous serious reaction should be discussed before another dose.
Call 911 for trouble breathing or swelling of the tongue or throat. Not sure whether a reaction is expected? Contact a healthcare provider or call 811 for advice. Seek care promptly if symptoms are worrying or getting worse.
Useful to know
What has changed?
NACI’s May 2026 update recommends quadrivalent ACYW for routine programs at 12–23 months as C-only products leave the Canadian market. The July 2026 federal schedule lists ACYW for Ontario at 12 months and Grade 7.
Does my child need another dose now?
NACI does not recommend an extra ACYW dose just because a child already received Men-C-C at 12–23 months. Individual risks and later adolescent vaccination still need review. Bring the original record to the clinic.
Ingredients & more detail
Check the exact product
Ask the clinic for the product name. Its official Canadian product information (product monograph) lists ingredients, packaging, side effects and precautions. This page is a short overview, not a complete safety list.
Your next step
Bring the immunization record and a list of questions to the visit. Ask which doses count, what comes next and how to report new doses to public health.
