There are very few reasons why children cannot be vaccinated.
A vaccine should not be given to children who have had a severe (life-threatening) reaction to a previous dose of the same vaccine or any ingredient in the vaccine. If your child:
has a bleeding disorder (for example haemophilia, where their blood does not clot properly), or
has had a fit not caused by a raised temperature
speak to your GP, practice nurse or health visitor before your child has any vaccination.
A small number of babies and children should not have a routine vaccination due to health reasons. Your GP or nurse can give you more information and answer any concerns you have about vaccinations.
Children with a weakened immune system
A small number of children have a weakened immune system (an immune system that does not work as well as it should). This may be due to a health problem or treatment they are having for a condition (such as cancer) or following a transplant. These children should not usually have live vaccines. Live vaccines include the MMR, rotavirus and flu nasal-spray vaccines.
If your child has a weakened immune system, speak to your GP, nurse or health visitor before they are due to be vaccinated.
There are no other reasons why your child or baby should not have a vaccination.
