Protect yourself and your family against invasive meningococcal disease (IMD) with expert Meningitis B vaccination services. Same-day appointments available.

Meningitis is a serious infection of the protective membranes surrounding the brain and spinal cord. Invasive Meningococcal Disease (IMD) is a severe bacterial infection that can cause meningitis and septicaemia (blood poisoning).
Meningitis is inflammation of the meninges (protective membranes covering the brain and spinal cord). It can be caused by bacteria, viruses, or fungi. Bacterial meningitis is the most serious form and requires immediate medical attention.
Meningococcal group B bacteria is the leading cause of bacterial meningitis in the UK, particularly affecting babies, young children, teenagers, and young adults.
Invasive Meningococcal Disease (IMD) occurs when meningococcal bacteria enter the bloodstream or meninges. It can cause meningitis, septicaemia (blood poisoning), or both simultaneously.
IMD is a medical emergency that can progress rapidly. Without prompt treatment, it can lead to serious complications including brain damage, hearing loss, limb amputation, or death.
The Meningitis B vaccine is the most effective way to prevent IMD caused by group B bacteria. Since its introduction in the UK childhood immunisation programme in 2015, cases of MenB disease in babies have fallen by over 75%. Vaccination not only protects the individual but also helps reduce transmission in the community.
Early recognition of symptoms is crucial. Meningitis and septicaemia can develop rapidly, so immediate medical attention is essential if you suspect these conditions.
Sudden onset of high temperature
Intense, persistent headache
Difficulty bending neck forward
Dislike of bright lights
Persistent vomiting
Altered mental state, difficulty waking
Convulsions or fitting episodes
Severe aches and pains
Unusual, moaning cry
Not feeding or vomiting
Not wanting to be held, fretful
Difficult to wake, lethargic
Soft spot on head is tense or bulging
Unusual skin colour or appearance
Breathing faster than normal
A non-blanching rash (spots or blotches that don't fade when pressed with a glass) is a sign of septicaemia and requires immediate emergency medical attention. However, the rash may appear late or not at all, so do not wait for a rash if other symptoms are present.
Glass Test:
Press the side of a clear glass firmly against the rash. If the spots don't fade and you can still see them through the glass, seek emergency medical help immediately by calling 999.
Latest guidance from the UK Health Security Agency (UKHSA) for managing suspected invasive meningococcal disease.

Immediate single dose of IV/IM Ceftriaxone for suspected meningococcal infections:
Dose 2g stat
Dose 2g stat
Dose 80-100 mg/kg (maximum 4g per dose)
Immediate single dose of IV/IM Benzylpenicillin sodium for suspected meningococcal infections:
Dose 1.2g
Dose 600mg
Dose 300mg
This guidance is for healthcare professionals managing suspected IMD cases. If you suspect meningitis or septicaemia, call 999 immediately or go to your nearest A&E department. Do not delay seeking emergency medical care.
Understanding how meningococcal bacteria spread helps you take preventive measures to protect yourself and others.
Spread through respiratory droplets from coughing, sneezing, or kissing. Close and prolonged contact increases risk.
Caused by Neisseria meningitidis bacteria. Group B is the most common strain in the UK, followed by groups W, Y, and C.
University halls, military barracks, boarding schools, and other crowded living environments increase transmission risk.
