A new vaccine, for Meningococcus B, will soon be available for babies. What, another vaccine? Do we really need it?
I would say – absolutely yes.
Meningococcus causes meningitis, and blood infection (septicaemia) – sometimes leading to limb amputation or brain damage. Approximately 1:10 people affected die.
As a paediatrician, I’ve seen healthy children become seriously ill within hours. Most recover, but, inexplicably, some don’t, and I’ve had to tell shocked parents that their child may not make it through the night.
Meningitis is an infection of the meninges – the thin protective layer covering the brain and spinal cord. It can affect any age, but predominantly under fives, and, particularly, under ones. Teenagers/young adults are also susceptible.
In the UK, it’s usually caused by a virus –and recover is generally complete. However bacterial meningitis is far more dangerous – and the Meningococcus bacteria, of which there are several strains, is the main culprit. It normally lives harmlessly in the nose and throat, but sometimes invades the blood, causing the illness.
The UK vaccination programme already protects against some meningitis types – the bacteria – Haemophilus, Pneumococcus, Meningococcus strain C, and the viruses – Measles and Mumps.
A new vaccine against Meningococcus A, C, W and Y will soon be offered to young adults, plus the new B vaccine for infants.
Meningococcal vaccines are between 85 -100% effective initially – much less so in young children. They are usually safe but can cause pain/redness, vomiting, headaches, drowsiness or irritability. Occasionally, allergic reactions, or, rarely, neurological problems may occur. Protection wanes over time, so teenagers are given boosters. However, vaccination reduces the number of people carrying the bacteria, thus reducing infection risk for the whole community.
If you think someone may have meningitis, look out for:
Headache, stiff neck, photophobia (dislike of bright light), vomiting, drowsiness or confusion and fever. The typical rash (called petechial) is red but doesn’t fade when pressed. It isn’t always present, but if you see it, you must seek medical help urgently.
Sometimes, particularly youngsters, are so ill, that the classic signs aren’t obvious. The child may have a temperature, but, equally, may seem cold. They make look blue, cry incessantly (often high-pitched), refuse feeds, have convulsions or become unconscious. In young babies, their fontanelle (‘soft spot’) may bulge and feel tense.
It is important to treat rapidly. Antibiotics will kill the bacteria, but, if severe, intensive care may be necessary.
To give some perspective – approximately 3000 people will get bacterial meningitis/septicaemia in the UK this year. The incidence has decreased due to vaccination.
Knowing the signs could save a life. Always have a low index of suspicion – an unnecessary visit to A&E is far better than delayed treatment. I myself rushed my young son there, late one night. Embarrassingly, he made a miraculous recovery a soon as the doctor (my colleague) examined him – I did eventually live it down at work.

I have to point out that I am partial to a Rosé. In fact, it is one of my favourite types of wine. That does not mean that all Rosé is equal however. This Shiraz Rosé from Jacob’s Creek is the official wine of Wimbledon. It is fresh, fruity and well balanced. It goes well with strawberries and cream of course, otherwise it would have no place at Wimbledon. This is a crisp wine with characters of fresh berry fruit. It has a finish of tempered spice and quince. This is a perfect summer rosé you can’t go wrong with. It is dark in colour which usually means the rosé is very sweet but this is not the case here. Great taste and well balanced.
