Meningococcal B (MenB) vaccine

​​​​What is me​ningococcal B?

Meningococcal group B bacteria is a serious cause of life-threatening meningitis (infection of the lining of the brain)​ and septicaemia (blood poisoning).  O​verall, MenB disease is rare but the age group most affected are very young babies.​​

How and when the vaccine is​ given

Since 1 September 2015, all babies born on or after 1​ May 2015 are eligible for the MenB vaccine. This vaccine is offered alongside other routine vaccinations at the following ages: 

  • ​​2 months
  • 4 months

The vaccine is called Bexsero and it's given as an injection in the thigh.

Baby / child immunisations​

Vaccine safe​ty and side effects

Since the vaccine was licensed, almost a million doses have been given, with no safety concerns identified.​

Like all vaccines, the MenB vaccine can cause side effects, but studies suggest they're generally mild and don't last long. The most common side effects are:

  • fever (raised temperature)
  • irritability
  • tenderness and redness at the injection site 

Treating a raised temperature after the vaccine​

​Your baby is likely to develop a raised temperature within 24 hours of​ having the ​vaccine. ​To reduce the risk of fever, it's recommended you give your baby infant paracetamol just after they have their MenB vaccine. 

Your GP will give you an information leaflet about paracetamol at your vaccination appointment.​ Follow the instructions in the leaflet for the correct dose. 

If you're not sure, get advice from your pharmacist, GP or health visitor.​​

Getting the vaccine privately for older children

​The MenB vaccine has become available again for private use. If you want to vaccinate your older child (born before 1 May 2015), you will need to arrange with your GP to buy the vaccine privately. 

Symptoms of meni​ngitis​

The early symptoms of meningitis are similar to flu symptoms.

You need to be aware of all the signs and symptoms.
