Meningococcal conjugate type C (MenconC) vaccine

Learn about the MenconC vaccine, effectiveness, side effects, and safety

Disease it protects from

The MenconC vaccine protects against meningococcal disease caused by Neisseria meningitidis type C bacteria.

Who should get this vaccine

As part of the routine immunization schedule, children get this vaccine starting at age 4 months. You may also get this vaccine after close contact with someone with type C meningococcal disease.

Who may not be able to get this vaccine

You may not be able to get this vaccine if:

  • You have an allergy to any part of the vaccine. Be sure to tell your healthcare provider about any allergies you may have.
  • You had a severe (serious) or unusual side effect after this vaccine or one like it.

If either of these apply, check with your healthcare provider or a public health nurse before you get the vaccine.

Although you can get the vaccine if you have a mild illness such as a cold or fever, it’s best to stay home until you are feeling better to prevent spreading the illness to others.

Doses

Children need 2 doses, which are usually given at ages 4 and 12 months.

You need fewer doses if you get your first dose after age 12 months. However, it is not recommended to wait to get your baby immunized, because babies have a high risk of getting this disease.

If you’re getting this vaccine because you had contact with someone with type C meningococcal disease, your healthcare provider will tell you how many doses you need.

Other vaccines that protect against the same diseases

MenC-ACYW protects against types A, C, Y, and W-135 meningococcal disease. Grade 9 students can get this vaccine as part of the school immunization program. This will boost their protection against type C meningococcal disease and protect them from types A, Y, and W-135.

You may also get this vaccine if you travel to an area that has a high risk of meningococcal disease or you have other health conditions.

Children who get MenC-ACYW don’t need MenconC.

Men-B is a vaccine that protects against type B meningococcal disease. You may also need this vaccine along with the MenC-ACYW vaccine if you have certain types of health conditions.

Get the vaccine

You can get the vaccine at your local public health or community health centre.

MenconC and other vaccines

You can get a MenconC vaccine at the same time, any time before, or any time after most vaccines. Check with your healthcare provider or public health nurse about when you can get or if you need MenconC vaccine if you had another meningococcal vaccine, because there is a waiting period.
