How to treat fever after vaccination?
Keep your child cool by making sure they don’t have too many layers of clothes or blankets on and feed them frequently. A dose of infant paracetamol or ibuprofen liquid may help reduce your child’s fever. Read the instructions on the bottle very carefully. You may need to give a second dose eight hours later. It is not recommended that these medicines are given before or after vaccination in anticipation of a fever.
Are some babies allergic to vaccines?
Very rarely, children can have an allergic reaction soon after immunisation. This reaction may be a rash or itching affecting part or all of the body. The doctor or nurse giving the vaccine will know how to treat this. It does not mean that your child should stop having immunisations. Even more rarely, children can have a severe reaction, within a few minutes of the immunisation, which causes breathing difficulties and can cause the child to collapse. This is called an anaphylactic reaction. A recent study has shown that there is only one anaphylactic reaction in about a million immunisations. The people who give immunisations are trained to deal with anaphylactic reactions and children recover completely with treatment. An anaphylactic reaction is a severe and immediate allergic reaction that needs urgent medical attention.
What if my baby is ill on the day of the appointment?
If your baby has a minor illness without a fever, such as a cold, they should have their immunisations as normal. If your baby is ill with a fever, put off the immunisation until they have recovered. This is to avoid the fever being associated with the vaccine, or the vaccine increasing the fever your child already has. If your baby: has a bleeding disorder (for example haemophilia, in which the patient’s blood does not clot properly), or has had a fit not associated with fever, speak to your doctor, before your child has any immunisation.
