The 4-in-1 pre-school booster is given to children aged 3 years, 4 months old before they start school.
Most children can have the 4-in-1 pre-school booster. They cannot have it if they've had a serious allergic reaction to an ingredient in it.
You can check the ingredients in the 4-in-1 pre-school booster by asking to see the patient leaflet or searching for it online.
Your GP surgery will usually contact you to arrange your child's 4-in-1 pre-school booster. Speak to your GP surgery if you have not been contacted.
Side effects of the 4-in-1 pre-school booster include swelling or pain where the injection was given, feeling tired and a high temperature.
