What Is the Difference Between the ACWY and B Meningitis Vaccines?

difference between meningitis acwy and b vaccines explained

Meningitis is a serious infection that can affect anyone, but certain age groups and travellers are more at risk. Thankfully, there are vaccines that help protect against this illness. Two of the main vaccines available in the UK are the Meningitis ACWY vaccine and the MenB vaccine. While they both protect against meningitis, they target different strains of the disease.

If you’re unsure which vaccine is right for you or your child, this guide will help explain the key differences in a simple and easy-to-understand way.

What Is Meningitis?

Meningitis is an infection of the protective membranes that surround the brain and spinal cord. It can be caused by viruses or bacteria. Bacterial meningitis is the more severe form and can lead to life-threatening complications or long-term issues like hearing loss, brain damage, or even death if not treated quickly.

Common symptoms include:

  • Fever
  • Headache
  • Stiff neck
  • Sensitivity to light
  • Vomiting
  • Cold hands and feet
  • Confusion or drowsiness

In babies, you may also notice a high-pitched cry or a bulging soft spot on the head.

Meningitis Vaccine Types in the UK

There are different strains (types) of the bacteria that cause meningitis. The main vaccines used in the UK include:

  • Meningitis ACWY vaccine: Protects against four strains – A, C, W and Y.
  • MenB vaccine: Protects against strain B, which is the most common cause of bacterial meningitis in the UK.

ACWY vs MenB – What’s the Difference?

Meningitis vaccines are essential in protecting against various strains of the meningococcal bacteria that can cause serious illness. Two key vaccines given in the UK are the ACWY vaccine and the MenB vaccine. While both serve the same purpose – to protect against meningitis – they target different bacterial groups and are recommended for different age groups and situations.

The ACWY vaccine protects against four types of meningococcal bacteria: A, C, W, and Y. These strains, although less common in the UK, are known to cause serious outbreaks, especially in group settings such as universities. This vaccine is usually given to teenagers around the age of 14 (school year 9) and to students heading off to university. It’s also required for certain travel destinations, such as Saudi Arabia, particularly for Hajj or Umrah pilgrimages.

On the other hand, the MenB vaccine specifically protects against meningococcal group B – the most common cause of bacterial meningitis in the UK. It is mainly given to babies at 8 weeks, 16 weeks, and again at 1 year as part of the routine childhood immunisation schedule. It may also be recommended for older children or adults with specific medical conditions that increase their risk.

Do You Need Both?

Yes, some people may need both vaccines for full protection. Since each vaccine protects against different strains, getting both can offer broader coverage. For example, a university student may already have had the MenB vaccine as a baby and will now be offered the ACWY vaccine before leaving for university.

Travellers to certain parts of Africa, Asia, and the Middle East may also benefit from both vaccines, depending on the destination and duration of travel.
