Meningococcal C (MenC)

The Meningococcal C (MenC) vaccine helps protect against meningitis and septicaemia (blood poisoning) caused by meningococcal group C bacteria.

Your baby will be offered the MenC vaccine when they are 3 months old. They will also be offered the combined Hib/MenC vaccine between 12 and 13 months of age, to boost their protection against MenC infections. These vaccines do not protect against meningitis and septicaemia caused by meningococcal group B bacteria.

Questions and answers:

How effective is the MenC vaccine?

Since the vaccine was introduced, the number of babies under the age of one with the group C disease has fallen by about 95 per cent across the UK. A booster dose of MenC in the second year of life is needed to provide longer-term protection.

Are there any possible side effects?

Your baby may have redness, swelling or tenderness where they had the injection. About half of all the babies who have the vaccine may become irritable, and about 1 in 20 could get a mild fever.

What is MenC?

MenC (meningococcal group C bacteria) can cause meningitis (an infection of the lining of the brain) and septicaemia (another name for blood poisoning) refers to a bacterial infection in the blood. Meningitis and septicaemia are both very serious – they can cause permanent disability and death and the symptoms can come on quickly – so you must get treatment straight away. After babies, young people are particularly vulnerable to meningococcal infection.

How do I do the glass test? 

Someone with septicaemia may develop a rash which will not fade under pressure. You can check by doing a ‘glass test.’
