NATIONAL IMMUNISATION PROGRAMME-Introduction to VPDs, EPI :- World & India , UIP
VACCINE PREVENTABLE DISEASES:
- An infectious disease for which an effective preventive vaccine exists.
- If a person dies from it, the death is considered a vaccinepreventable death
- Tuberculosis
- Diphtheria
- Pertussis
- Poliomyelitis
- Measles
- Tetanus
- Hepatitis B
- Japanese Encephalitis
FULLY IMMUNIZED CHILD:
- A child who received :
- One dose of BCG, Three doses of DPT and OPV, One dose of measles before one year of age.
EXPANDED PROGRAMME ON IMMUNISATION (EPI):
- EPI launched in 1974
- Build on pox infrastructure
- Targeted 6 diseases

Measles |
- Yellow fever in 1988
- For endemic countries only
- Given with measles vaccine
- Hepatitis B in 1992
- In high seroprevalence countries by 1995
- In all countries by 1997
- Haemophilus influenzae type b (Hib)
- Based on disease burden and capacity
- 2006 : all countries.
EPI IN INDIA:
- The Govt of India launched it’s EPI in 1978.
- Introduced BCG, OPV, DPT, & Typhoid-paratyphoid vaccines
- Objectives
- To reducing mortality, morbidity resulting from VPDs.
- To achieve a self sufficiency in vaccine production.
- Target :- at least 80% coverage in infancy.
- As vaccination was offered through major hospitals & largely restricted to urban areas so coverage remained low.
- In 1983 tetanus toxoid vaccine for pregnant woman
MILESTONES IN THE IMMUNIZATION PROGRAM:
- 1978 : EPI introduced after smallpox eradication:
- BCG, DPT, OPV, Typhoid.
- Limited to mainly urban areas
- 1985 : Universal Immunization Program (UIP) introduced
- Expanded to entire country; Measles added.
- 1986 : National Technology Mission
Objectives:
- Monitoring under PMO’s 20 point programme
- Improve coverage with existing antigens
- Develop self sustainability in vaccine production
- 1990 : Vitamin-A supplementation.
- 1992 : Child Survival and Safe Motherhood Program.
- 1995:- India 1st conducted national immunisation day for polio eradication.
- 1997:- Reproductive and Child Health Programme
- National Polio Surveillance Project launched as WHO & GOI collaboration.
- 2001:- National Technical Advisory Group On immunisation formed
- 2005:- National Rural Health Mission
OBJECTIVES:
- To increase immunization coverage.
- To improve quality of service.
- To achieve self sufficiency in vaccine production & manufacturing of cold chain equipments.
- To establish reliable cold chain equipment and establish a good surveillance network.
- To introduce a district wise system monitoring & evaluation
- To train health personnel.
- Immunization of pregnant women against tetanus
- Immunization of children in their first year of life against 6 VPDs.
TARGETS:
- To achieve 100 % coverage of pregnant women with 2 doses of TT.
- At least 85% coverage of children under one year (with 3 doses of DPT, OPV & one dose of BCG, One dose of Measles) by march 1990.
- Target was increased to cover 100% of infants as the vaccination programme became universalised in geographical coverage
- UIP was first started in 31 selected districts with plan of scale up to additional districts.
GOALS:
- Goal 1:Districts will provide efficient and safe immunization services to all infants and pregnant woman
- Goal 2: Contribute global polio eradication, measles mortality reduction and neonatal tetanus elimination
- Goal 3: UIP will have sufficient and sustainable funding with established adequate, accountable, efficient fund flows
- Goal 4: Sustain demand & reduce social barriers to access immunisation services
- Goal 5: Accelerated introduction of licensed new and under utilized vaccines against diseases with significant mortality and morbidity in India
- Goal 6: To monitor & use accurate, complete & timely data on vaccine preventable disease , AEFIs, antigen coverage & drop out rates by district
CHANNELS OF SERVICE PROVISION:
- Immunization services are provided through the existing Health Care Delivery System. (MCH centers, PHC, CHCs, Hospitals, Dispensaries).

Indian academy of pediatrics (IAP) classification of malnutrition is based on weight for age.
IAP designates a weight of more than 80% of expected for age as normal.
Grades of malnutrition are ?
- Grade I → 71-80%
- Grade II → 61-70%
- Grade III → 51-61%
- Grade IV → 50%

INTRODUCTION OF PENTAVALENT VACCINE (DPT + HEP-B + HIB)
- India introduced pentavalent vaccine containing DPT, hepatitis B and Hib vaccines in two states viz.
- Kerala and Tamil Nadu under routine immunization programme from December 2011.
- DPT and hepatitis B vaccination requires 6 injections to deliver primary dose
- New antigen, i.e., Hib has been added which protects against Haemophilus influenza type B (associated with pneumonia and meningitis) and the number of injections are reduced to 3.
- The vaccine has been expanded to 6 more states, i.e.,
- Haryana, Jammu and Kashmir. Gujarat, Karnataka, Goa and Puducherry in 2012-13.
- Further expansion is planned to 11 states in October 2014 and rest of 15 states from April 2015.
Exam Important
- Give BCG, OPV, DPT, measles vaccines and vitamin A is given if 3year old in unimmunized
- 18 month old child, has received one dose of DPT and OPV at 2 months of age should be given BCG, 2nd dose of DPT and OPV
- Grade III malnurtition according to IAP is 51-60 %
- In a 8 yrs old unimmunized child Pertusis & Salk vaccine can not be given
- In national immunization shedule of India, measles vaccine is given at 9 Months
- In National immunization schedule TT, OPV & Measles are given.
- In the WHO recommended EPI Cluster sampling for assessing primary immunization coverage, the age group of children to be surveyed is 12-23 months
- In the UIP blindness can be prevented by the administration of Measles vaccines
- Weight of child is 70% of normal according to IAP classification, categorised in Moderate
