While most mums will be understandably worried, it’s actually perfectly common for your child to develop a fever after an immunisation.
Vaccines contain a weakened or dead version of viruses or bacteria that stimulate your little one's body to produce antibodies without developing the illness. These antibodies will help them fight off the disease if they come into contact with the real, full strength virus or bacterium down the line.
Some infants can react to the vaccine and develop a slight fever, but this should be gone after a couple of days.
However mums will want to do everything they can to make their little ones feel better, especially after the shock of a needle.
To help your infant, make sure they get plenty of restful sleep and also try to make sure they keep cool and hydrated.
If your baby is still uncomfortable, you can treat their fever with a medicine containing infant paracetamol, such as CALPOL Infant Suspension. Just make sure to follow medicine instructions and contact your GP if symptoms persist.
