Complications of Hib infection
A Hib infection can cause serious conditions including:
- infection of the lining of the brain and spinal cord (meningitis)
- a severe immune reaction (sepsis)
- infection of part of your windpipe (epiglottitis)
- infection of the lungs (pneumonia)
You can become very ill with these conditions and will need treatment in hospital.
Even with successful treatment, there may be lasting effects such as hearing loss, seizures, loss of limbs and learning disabilities.

Treatment for Hib infection
The main treatment for a Hib infection is antibiotics. You'll usually need to be treated in hospital.
You may be given oxygen and other medicines such as steroids, depending on your symptoms. Other treatments, including surgery, may also be needed.
If you have a Hib infection, your close contacts, such as anyone you live with, may be offered antibiotics to stop them getting ill.
Hib vaccination
Vaccination is the best way to prevent serious Hib infections.
The 6-in-1 vaccine protects against Hib and is offered to children as part of the NHS vaccination schedule.
It's given in 4 doses at 8 weeks, 12 weeks, 16 weeks and 18 months old.
If your child has missed their 6-in-1 vaccinations, you can ask your GP about how they can get it.
How Hib spreads
Hib is spread by sneezing and coughing, the same as how colds and flu spread.
Hib bacteria can live in the nose and throat of many healthy people without causing any problems. But healthy people can still pass it on and cause others to get ill.
Some people are more at risk of getting seriously ill from a Hib infection, including:
- babies and young children
- people with a weakened immune system, including people who have had their spleen removed
- older people
