What is the pneumococcus?
Pneumococcus is a germ (bacterium) which can cause pneumonia, meningitis and some other infections. Pneumonia caused by pneumococcus occurs in about 1 in 1,000 adults each year. Pneumococcal infection can affect anybody. However, young children, older people and some other groups of people are at increased risk of developing a pneumococcal infection.
Who should be immunised against the pneumococcus?
Three groups of people should be immunised:
- People over 65 years
- Certain other people who are at risk (detailed below).
Immunisation against pneumococcus is part of the routine childhood immunisation programme. The routine schedule consists of three injections which are normally given at age 2 months, 4 months and between the ages of 12 and 13 months.
All older people
All people aged 65 or over should be immunised. This consists of a one-off injection.
Other at-risk groups
Any person over the age of 2 months in an at-risk group should be immunised. That is, if you:
Types of vaccine
There are two types of vaccine to protect against pneumococcal infection:
Both are given by injection. Both vaccines contain several components to protect against several types (strains) of the pneumococcus. They differ in the number of types that they protect against. Also, the PPV does not work very well in children under the age of 2 years. Therefore, the PCV vaccine is given to children under the age of 2 years.
The PCV and PPV vaccines do not contain thiomersal; they do not contain live organisms and so cannot cause any of the diseases against which they protect.
The vaccines stimulate your body to make antibodies against pneumococcal germs (bacteria). These antibodies protect you from illness should you become infected with pneumococcal bacteria. The vaccines protect against many (but not all) types of pneumococcal bacteria.
Routine immunisation schedule for children aged under 2 years
Children are routinely offered three injections of PCV at age 2 months, 4 months and between 12 and 13 months. The first two are usually given at the same time as the DTaP/IPV(polio)/Hib injection - this stands for 'diphtheria, tetanus, pertussis (whooping cough)/polio/Haemophilus influenzae type b' - (but given in a different part of the body with a separate needle and syringe). The third dose, at between 12 and 13 months, is usually given at the same time as the Hib/MenC vaccine - this stands for 'H. influenzae type b/meningitis C' - and the MMR vaccine (measles, mumps and rubella).
If a child between the ages of 1 and 5 years has not had any previous dose of PCV, or has only had one previous dose, then a single dose of PCV should be given.
Immunisation schedule for older people and those at risk
People aged 65 and over and all other people at any age in any of the at-risk groups listed above should be immunised with PPV. PPV is normally given just once. It provides lifelong protection against many types of pneumococcus.
Children who are in an at-risk group and have previously had their routine immunisations with PCV should also have one injection of PPV as soon as possible after their second birthday (but at least two months after the final dose of PCV).
Children who are in an at-risk group under the age of 5 years who have not previously had routine immunisations with PCV will need both PCV and PPV. The dose schedules depend on age and circumstances. Your doctor will advise you about this.
Notes for some special groups
- If you are about to have your spleen removed, ideally you should be immunised 4-6 weeks before the operation, but at least two weeks before. If this is not possible, you should be immunised two weeks after the operation.
- If you are about to undergo chemotherapy or radiotherapy, ideally you should be immunised 4-6 weeks before commencing treatment.
- Generally, booster doses of vaccine are not required in addition to those described above. However, in people without a working spleen or with certain chronic kidney diseases, the antibody level gradually falls over time. Therefore, these people should have a booster dose every five years.
Are there any side-effects?
Pneumococcal immunisation usually causes no problems. Mild soreness and a lump at the injection site sometimes occur. A mild high temperature (fever) may develop for a day or so. These side-effects are usually minor and soon go away.
Who should not receive the pneumococcal immunisation?
- If you have had a severe reaction to a previous dose of pneumococcal vaccine.
- A dose of vaccine may be delayed if you are ill, or your child is ill, with a high temperature (fever).
- There is no reason to delay a dose of vaccine if you have a minor infection, or your child has a minor infection, such as a cough, cold or snuffles.
The vaccine may be given to pregnant women when the need for protection is required without delay. It is safe to have if you are breast-feeding.
