RESUMEN
OBJECTIVE: To evaluate all steps of pulse polio immunization on special sub national immunization day. METHODS: On a sub-national immunization day (SNID), 120 booths were randomly selected from 662 booths by probability proportionate to size (PPS) sampling technique. RESULTS: It was observed that attendance in the district level meeting was thin (30%). 34% workers were doing this work for the first time without any training. 40% of the vaccinators were neither working according to micro plan nor were same as mentioned in the micro plan. Supervision too was found deficient. CONCLUSION: In a sustained and long drawn programme like IPPI, sustaining the interest and motivation of health personnel is paramount. This paper emphasises the importance of continued re-orientation training to keep them motivated and updated.
