Immunization is a way of protecting the human body against infectious diseases through vaccination.
Immunisation prepares our bodies to fight against diseases in case we come into contact with them in the future. Babies are born with some natural immunity which they get from their mother and through breast-feeding. This gradually wears off as the baby's own immune system starts to develop. Having your child immunized gives extra protection against illnesses which can kill. Even if the baby is brought late for vaccinations, she should still receive all the vaccinations.
