Meningitis B: What Parents Should Know Following the Kent Cases

Recent reports of meningococcal disease in Kent have understandably caused concern among parents across the South East and London. While these cases remain rare, meningococcal infection can become serious very quickly, which is why outbreaks tend to prompt renewed discussion about vaccination and prevention.

For families with teenagers — particularly those approaching sixth form or university age — it is sensible to understand the risks and the role vaccination can play in reducing them.

What Is Meningitis B?

Meningococcal disease is caused by the bacterium Neisseria meningitidis. It can lead to two life-threatening conditions:

• Meningitis – inflammation of the lining around the brain and spinal cord

• Septicaemia – bloodstream infection which can progress rapidly

There are several strains (serogroups) of meningococcal bacteria. In the UK, group B (MenB) currently causes the majority of cases in children and young adults.

Although meningococcal disease is uncommon, it can develop rapidly and requires urgent treatment.

How does meningococcal infection spread?

The bacteria live in the back of the nose and throat and are spread through close contact with respiratory secretions. This can occur through:

• Coughing or sneezing

• Kissing

• Sharing drinks, bottles or utensils

• Close social contact in shared living spaces

  
  

Many people carry the bacteria without becoming ill, but they can still pass it to others.

Settings where young people mix closely — such as schools, university halls of residence and social environments — can increase the risk of transmission.

Why teenagers and university students are a higher-risk group

Adolescence and early adulthood represent a second peak in meningococcal disease risk.

Several factors contribute to this:

• Increased social mixing

• New living environments

• Close contact with large numbers of people

• Higher rates of bacterial carriage in this age group
  

This is why the NHS offers the MenACWY vaccine to teenagers, which protects against four meningococcal strains (A, C, W and Y).

However, MenACWY does not protect against MenB, which remains the dominant strain in younger people in the UK.

The meningitis B vaccine (Bexsero)

The MenB vaccine (Bexsero) was introduced into the UK infant vaccination programme in 2015.

Studies following its introduction showed the vaccine to be highly effective, reducing cases of MenB disease in vaccine-eligible infants by around 80%.

For babies, the schedule is:

• 8 weeks

• 16 weeks

• 12 months

However, children born before 2015 were not routinely offered the vaccine, and some families chose to obtain it privately.

Should older children and teenagers consider the meningitis B vaccination?

For teenagers who did not receive the vaccine as infants, private vaccination may be worth discussing, particularly if they are approaching:

• sixth form boarding environments

• gap year travel

• university halls of residence
  

Although meningococcal disease is rare, the potential severity of infection means many families prefer to reduce risk where possible.

The usual private schedule for older children and adults is two doses given at least one month apart.

What if a child had meningitis B vaccination privately many years ago?

A smaller group of children received MenB vaccination privately before the NHS programme began.

If this was around 8–10 years ago, protection may have waned. However, immune memory is likely to remain.

Evidence shows that a booster dose produces a strong immune response, suggesting that earlier vaccination still “primes” the immune system.

In practice, many clinicians consider a booster dose before university reasonable for those vaccinated long ago, although there is currently no national recommendation requiring this.

If teenagers are vaccinated now, will they need another dose before university?

This is one of the most common questions parents ask.

The honest answer is: we do not yet know exactly how long protection lasts when vaccination occurs during adolescence.

Current evidence suggests:

• Protective antibody levels decline gradually over several years

• Immune memory remains, allowing a strong response to booster vaccination
  

For this reason, if a teenager receives MenB vaccination at 13–16 years of age, it is possible that a booster may be considered again before university, particularly if several years have passed.

However, future national guidance may evolve as more long-term data becomes available.

A balanced perspective on vaccination

Meningococcal disease is rare, and most children will never encounter it. However, when it does occur it can progress rapidly and become life-threatening.

Vaccination cannot eliminate risk completely, but it significantly reduces the likelihood of severe infection.

Common side effects of the Meningitis B vaccine include:

• Soreness at the injection site

• Fever

• Fatigue

• Headache

  
  

Serious side effects are extremely uncommon.

When to seek urgent medical help

Parents should seek urgent medical attention if a child develops symptoms such as:

• Fever with severe headache

• Neck stiffness

• Sensitivity to light

• Vomiting

• Confusion or drowsiness

• A rash that does not fade when pressed
  

Early treatment is critical.

How we approach MenB vaccination at Mews Medical

At Mews Medical we take an individualised approach to meningococcal vaccination.

For families with teenagers we typically discuss:

• whether the child received MenB as an infant

• previous private vaccination history

• timing relative to sixth form, boarding or university

• individual risk tolerance
  

For some families, vaccination during the teenage years provides reassurance. For others, it may be reasonable to wait until closer to university, when risk increases again.

Our role is to help families make an informed decision based on current evidence and their child’s circumstances.
