Routine primary immunization: status in two district of West Bengal.
The study was conducted at Birbhum and Purba Medinipur districts of West Bengal to assess the routine primary immunization coverage following 40 cluster sampling technique was used to study 320 children in each of the districts. BCG coverage was found to be 79.69% at Birbhum and 84.38% at Purba Medinipur. Only 62.81% children at Birbhum and 67.81% children at Purba Medinipur received all the three primary doses of DPT. Regarding OPV, coverage with three primary doses were only 65% and 66.88% at Birbhum and Purba Medinipur respectively. Measles vaccine coverage was very poor at both the districts, 55.94% at Birbhum and 62.5% at Purba Medinipur. Full primary immunization was observed 53.13% and 61.56% in Birbhum and Purba Medinipur respectively. High drop-out rate was identified as a major deficiency in both the districts. Of the children who received at least one routine vaccine, more than 1/3rd at Birbhum and more than 1/4 th at Purba Medinipur did not turn up later for completion of their primary vaccine doses. It is evident that routine immunization coverage was poor in both the districts and it seems there has been no improvement in situation for last few years. It will influence not only the child morbidity and mortality situation but also will jeopardize the paralytic polio eradication programme. Urgent intervention should be undertaken to address the large number of non-immunized children as well as high proportion of drop-outs.
