Vaccin antipneumococcique pour les bébés et les enfants

About pneumococcal vaccine

Pneumococcus is a germ (bacterium) which can cause pneumonia, meningitis and some other infections. Pneumococcal infections can affect anybody, but they are particularly common in young children. Some pneumococcal infections are more serious than others.

Immunisation against pneumococcus is part of the routine childhood immunisation programme in the UK. The routine schedule consists of two injections; the first at age 12 weeks and the second at one year.

There are two types of vaccine available to protect against pneumococcal infection, but only one of these works well in young children. It is called pneumococcal conjugate vaccine (PCV). The brand name of the vaccine usually used for childhood immunisation is Prevenar 13®.

The second type of vaccine is called pneumococcal polysaccharide vaccine (PPV) and is used for adults and for children over 2 years of age. There is another separate medicine leaflet called Pneumococcal vaccine for adults which provides more information about this vaccine. Adults and children aged 2 years or over can also have PCV, although this is not routinely provided by the NHS.

The vaccine stimulates your child's immune system to make antibodies against pneumococcal infections. These antibodies then help to protect your child from illness should they become infected with pneumococcal bacteria. The vaccine protects against many (but not all) types of pneumococcal bacteria.

Before your baby is given pneumococcal vaccine

Before your child is given PCV, make sure your doctor knows:

• Si votre enfant s'est senti mal récemment ou s'il a une température élevée (fièvre).

• Si votre enfant a déjà eu une réaction allergique à un vaccin ou à un médicament.

• Si votre enfant souffre d'une maladie qui le fait saigner plus que la normale, comme l'hémophilie.

• Si l'on vous a dit que votre enfant avait un système immunitaire affaibli.

Comment le vaccin est-il administré ?

• Avant que votre enfant ne reçoive le vaccin, demandez à lire la notice du fabricant. La notice du fabricant vous donnera plus d'informations sur le vaccin et vous informera sur les effets secondaires que votre enfant pourrait ressentir à la suite de la vaccination. Si vous avez des questions sur le vaccin, demandez conseil à votre médecin ou à votre infirmière.

• Your child will be given two doses of the vaccine. It is usual for the first to be given at 12 weeks and the second at one year. PCV will be given on the same visit as your child's other routine vaccines, but it will be given as a separate injection.

• The vaccine is usually given by injection into a muscle in their thigh or upper arm. However, if your child has a condition that makes them bleed more than normal, the vaccine can be given as an injection just underneath the skin.

Getting the most from the vaccine

• Si votre enfant a une température élevée (fièvre) ou est très malade au moment d'une vaccination prévue, le médecin ou l'infirmière peut recommander de retarder l'administration du vaccin. Une maladie mineure (comme une toux, un rhume ou un rhume de cerveau) n'interfère pas avec le vaccin. Si un report est conseillé, on vous donnera un autre rendez-vous pour la vaccination.

• Children who are particularly at risk from pneumococcal infections may need to have a dose of a different type of pneumococcal vaccine when they are a little older. This will be in addition to the two routine doses of PCV. This may be recommended, for example, for a child who has previously had pneumonia and been admitted to hospital.

Can pneumococcal vaccine cause problems?

Along with their useful effects, vaccines like most medicines can cause unwanted side-effects, although not every child experiences them. Pneumococcal immunisation often causes no problems, but the table below contains some of the side-effects which may occur. You will find a full list in the manufacturer's information leaflet supplied with the vaccine. Speak with a doctor or nurse if any of the following side-effects continue or become troublesome.

You will normally be asked by the doctor or nurse to wait several minutes after the immunisation to make sure that your child does not react badly to the vaccine. Although allergic reactions are extremely rare, you should seek urgent medical advice if your child becomes breathless, or if any swelling or a rash develops within a few days of the immunisation.

Si vous présentez d'autres symptômes qui pourraient être dus au vaccin, parlez-en à votre médecin ou à votre pharmacien.
