Immunization

Immunization is an important and effective health intervention for children to fight against various infectious agents causing diseases.

It has helped millions of children to get protected against infectious and life-threatening diseases.

   Specific vaccines are administered to children at certain age and with the recommended dosage as children are susceptible to certain diseases at certain ages. This is important for vaccines to be effective. For example, polio occurs most frequently in children below the age of 5. Because of this, polio vaccines are given to children of those ages to prevent harm caused by the disease.
