The question of which meningitis vaccine is needed, and whether both the MenACWY and MenB vaccines are necessary, is one that comes up regularly for parents of teenagers, students heading to university, and adults reviewing their vaccination history. The short answer is that they protect against different strains of the same bacteria, both matter, and for many people the answer is both. But the detail of who gets what, when, and through which route is worth understanding properly.
What Is Meningitis and Is It Contagious?
Meningitis is an infection of the membranes surrounding the brain and spinal cord. It can be caused by viruses, bacteria, or, rarely, fungi. Bacterial meningitis is the most serious form, capable of progressing to life-threatening illness within hours.
Is meningitis contagious? Yes, the bacteria that cause meningococcal disease can be spread through respiratory droplets and close, prolonged contact, such as kissing, coughing, or living in close quarters. However, the bacteria are relatively fragile and do not survive long outside the body, meaning it is not as easily spread as the flu or a cold. Many people carry the meningococcal bacteria harmlessly in their throats without becoming ill. It is prolonged close contact rather than brief casual exposure that carries the greatest risk.
In the UK, the most significant cause of bacterial meningitis is Neisseria meningitidis (the meningococcus), which exists in multiple strains (serogroups). Group B is the most common strain in the UK, but groups A, C, W, and Y also cause serious disease, particularly in certain populations and travel settings.
MenACWY vs MenB: What Each Vaccine Covers
The fundamental distinction between the meningitis vaccine types is which bacterial strains they protect against. Neither vaccine is a substitute for the other, and they work through different mechanisms.
| Feature | MenACWY Vaccine | MenB Vaccine (e.g. Bexsero) |
| Strains covered | Groups A, C, W, and Y | Group B only |
| Type of vaccine | Conjugate (non-live) | Outer membrane vesicle (non-live) |
| Example brands (UK) | Nimenrix, MenQuadfi | Bexsero, Trumenba |
| Doses (adults) | Single dose (boosters in some cases) | Two doses, typically 1–6 months apart |
| NHS: routine offer | Yes — teens (Year 9/10) and uni freshers (catch-up) | Yes — infants (8 weeks, 16 weeks, 1 year) |
| NHS: adults outside schedule | Not routinely (some exceptions) | Not routinely offered to adults |
| Private access | Yes — available from registered pharmacies | Yes — available from registered pharmacies |
| Travel use? | Yes — required for Hajj/Umrah; sub-Saharan Africa | Not typically a travel vaccine |

The MenB Vaccine: What It Protects Against
Group B meningococcal disease accounts for the majority of bacterial meningitis cases in the UK, making MenB protection the most relevant for most people in this country. The MenB vaccine (Bexsero is the most widely used brand in the UK) works by targeting proteins on the surface of the group B meningococcus, stimulating the immune system to produce antibodies that recognise and fight the bacteria.
In the UK, Bexsero is offered as part of the routine infant immunisation schedule at eight weeks, sixteen weeks, and one year of age. It is not currently part of the routine NHS offer for older children, teenagers, or adults, meaning that many adults have never received MenB protection. Private vaccination with the MenB vaccine is available for older children, teenagers, and adults who wish to address this gap.
Who Should Consider Private MenB Vaccination?
The groups for whom private MenB vaccination is most worth considering include:
- University students, especially those moving into halls of residence where close living and social contact increases transmission risk. This group faces a well-documented spike in meningococcal disease risk in the first weeks of the academic year.
- Teenagers who did not receive MenB in infancy and whose parents want broader meningococcal protection beyond the MenACWY vaccine received at school.
- Adults with medical conditions that increase their susceptibility to serious bacterial infections, such as asplenia or complement deficiency.
- Those with a known close contact who has had group B meningococcal disease.
The student meningitis vaccine question comes up frequently at the start of each academic year. The MenACWY vaccine is offered on the NHS to eligible students, but MenB is not, leaving a gap in protection against the most common strain. Private MenB vaccination at the point of going to university is an option many families choose to address this.
The MenACWY Vaccine: What It Protects Against
The MenACWY vaccine covers four meningococcal serogroups: A, C, W, and Y. In the UK, group C is now relatively uncommon thanks to a longstanding vaccination programme, but groups W and Y have been increasing in incidence, making the MenACWY vaccine particularly important in the current epidemiological context.
The MenACWY vaccine is offered on the NHS to teenagers in Year 9 or 10 as part of the school immunisation programme, and as a catch-up to university freshers who missed the teenage dose. It is also required for Hajj and Umrah pilgrims travelling to Saudi Arabia, and recommended for travellers to sub-Saharan Africa during the meningitis belt season.
For adults who missed the teenage dose and are not eligible for the NHS catch-up, a private MenACWY vaccine is available through registered pharmacies. A single dose is sufficient for most adults.
Do You Need Both MenACWY and MenB?
For many people, particularly teenagers and young adults who have not had both vaccines, the answer is yes. The two vaccines protect against different strains and are genuinely complementary, not interchangeable. MenB offers protection against the most common strain in the UK, while MenACWY covers strains that are increasing in prevalence and are particularly relevant for travel.
A pharmacist can review your vaccination history and advise on what, if anything, is missing. Many people who received the MenACWY vaccine at school have no MenB protection at all, and vice versa for infants who received MenB but not MenACWY.

Frequently Asked Questions (FAQ’s)
What is the difference between MenACWY and MenB vaccines?
MenACWY and MenB are two separate vaccines that protect against different strains of the Neisseria meningitidis bacteria. MenACWY covers serogroups A, C, W, and Y. MenB covers group B only, which is the most common cause of bacterial meningitis in the UK. They work through different mechanisms, require different dose schedules, and are not interchangeable. Many people need both.
Is meningitis contagious through casual contact?
The bacteria that cause meningococcal disease are spread through respiratory droplets and prolonged close contact, such as kissing, coughing, or sharing a living space. Casual brief contact, such as sitting near someone on public transport, does not typically carry significant risk. Many people carry the bacteria harmlessly. It is sustained close contact in households, schools, or student accommodation that presents the greatest transmission risk.
Should students get the MenB vaccine before university?
This is a question worth discussing with a pharmacist or GP. The student meningitis vaccine routinely offered through the NHS is the MenACWY vaccine, which covers groups A, C, W, and Y. The MenB vaccine, which covers the most common UK strain, is not routinely offered to this age group on the NHS. Many parents and students choose to arrange private MenB vaccination before starting university, particularly for those moving into shared accommodation in halls. A pharmacist can advise on eligibility and timing.
Is the MenB vaccine available for adults?
Yes. The MenB vaccine (Bexsero) is available privately for adults through registered pharmacies and clinics. It is not currently part of the routine NHS immunisation programme for adults, though it is recommended for certain medical risk groups. Adults who were not vaccinated in infancy and want MenB protection can arrange private vaccination. Two doses are required, typically one to six months apart.
How long does the meningitis vaccine last?
Protection duration varies by vaccine type. MenACWY vaccine protection in adolescents and adults is generally considered to last around five years, though boosters may be recommended for those at ongoing high risk, such as frequent travellers to sub-Saharan Africa or Hajj pilgrims. MenB protection from childhood vaccination may wane over time, and the need for boosters in adults is an area of evolving guidance. A pharmacist can advise on your individual history.
Can I get MenACWY and MenB at the same time?
In many cases, yes. MenACWY and MenB can be co-administered, meaning they can be given at the same appointment, though typically in different arms. Your pharmacist will confirm whether co-administration is appropriate based on your circumstances and any other vaccines being given at the same time. Giving both at once is convenient and is used routinely in some NHS programmes for eligible groups.
