Expanded Programme on Immunization:

Expanded Programme on Immunization was launched in 1978.

• It was renamed as Universal Immunization Programme in 1985 when its reach was expanded beyond urban areas.
• In 1992, it became part of Child Survival and Safe Motherhood Programme and in 1997 it was included in the ambit of National Reproductive and Child Health Programme. Since the launch of National Rural Health Mission in 2005, Universal Immunization Programme has always been an integral part of it.
• Universal Immunization Programme (UIP) is one of the largest public health programmes targeting close of 67 crore newborns and 2.9 crore pregnant women annually.
• It is one of the most cost-effective public health interventions and largely responsible for reduction of vaccine preventable under-5 mortality rate.
• Under UIP, immunization is providing free of cost against 12 vaccine preventable diseases:
• Nationally against 9 diseases – Diphtheria, Pertussis, Tetanus, Polio, Measles, Rubella, severe form of Childhood Tuberculosis, Hepatitis B and Meningitis & Pneumonia caused by Hemophilus Influenza type B
• Sub-nationally against 3 diseases – Rotavirus diarrhoea, Pneumococcal Pneumonia and Japanese Encephalitis; of which Rotavirus vaccine and Pneumococcal Conjugate vaccine are in process of expansion while JE vaccine is provided only in endemic districts.
• A child is said to be fully immunized if child receives all due vaccine as per national immunization schedule within 1st year age of child.
• The two major milestones of UIP have been the elimination of polio in 2014 and maternal and neonatal tetanus elimination in 2015.
