Immunization save lives as it protects children against dangerous diseases of childhood. Immunization is done by vaccines either injected or given by mouth. These vaccines make the immunity of child or child’s defences strong against many diseases. Most importantly, immunization only works if given before the attack of a disease. Children, who don’t get their immunization on time become the best candidates to get these diseases, they become weak with hampered growth and may die from malnutrition and other diseases. Colostrum (or first breast milk) is termed as first vaccine of new-born as it builds the child’s immunity to disease.
