POLIO “How can we continue to tolerate polio when we have the technical expertise to get rid of it?” Dr. Harry Hull
INTRODUCTION Approximately 2.5 million children under 5 years of age die every year as a result of diseases that can be prevented by vaccination.
Prevention • Pain • Permanent damage and disfigurement, • Death • Emotional suffering • Protects others
“The function of protecting and developing health must rank above that of restoring it when impaired” Hippokrates

M.O.H.S.S. • Main goal of immunization: • Reduction of morbidity and mortality rates in children under 5 years • Achieve vaccine coverage - 85% Districts • Achieve 90% coverage on National level • Maintain coverage rates • Drop-out rate less than 5% • Elimination of poliomyelitis • Elimination of measles by 2015
Immediate goals: • Reverse declining immunization coverage • DPT 3 coverage from 85% - 90% • TT2+ coverage from 65% - 90% (child bearing women) • TT2+ coverage from 75% - 90% (pregnant women)
Successes of vaccination • Immunization programme is an integral part of Primary Health Care – 1990 • Supplemental Immunization Activities– 1996 • Elimination of maternal & neonatal tetanus – 2001 • “Polio free” – 2009 • Decline in vaccine preventable diseases • Hepatitis B and Hib was added to EPI schedule – 09/2009 • Introduction guidelines for new vaccines are in place • 271 Primary Health care clinics, 43 health centres, 35 hospitals and outreach posts provide immunization services to reach every child. • All injection are given one needle and one syringe per child. • Continuous training for staff • EPI Surveillance Committees • Close co-operation between private and state sectors • NB! – programme 100% funded by government

So are we doing enough? No! But are we doing bad? NO!!!
Let's never forget… Vaccination is by far the best thing that has ever come out of medical science for reducing the burden of human suffering and premature death, especially among children.
