Awareness of pulse polio immunisation.

Mass polio immunisation campaign was launched in the national capital territory of Delhi with 2 doses of polio vaccine to be administered to children upto 3 years of age on October and December 4, 1994 respectively. Massive information, education & communication (IEC) efforts through mass media and interpersonal communication preceded the dates of the campaign. A study to assess the awareness of general population was carried out by interviewing 225 adult residents of Delhi using a structured questionnaire. These were drawn by two stage stratified random sampling. Zonewise assembly segments in the first stage and census enumeration blocks in the second stage formed the sampling frame. The study, carried out 3 days prior to date of administration of first dose of oral polio, revealed that 60.4% of population was aware of the programme being launched and 31.6% about aim of the programme. None of the respondents were aware of all the specific parameters put together correctly viz., objective, immunisation days, age group & immunisation status of children. The higher level of awareness was directly proportional to the level of education. The overwhelming success of the programme was indicated by immunisation of > 90% children upto 3 years of age all over Delhi in the first phase of the programme. The key to success of the programme despite low awareness is explained on the basis of unflinching efforts put in by vaccine centre level committees, integrated child development scheme (ICDS) and urban basic service (UBS) functionaries in mobilising people to reach various vaccination centres. Other states planning to launch such mass campaigns should pay attention to social mobilisation in addition to IEC efforts for successful completion of the programme.
