MIRANDA, Alcides S. de; SCHEIBEL, Ilóite M.; TAVARES, Mario R. G.  and  TAKEDA, Silvia M. P.. Assessment of immunization coverage for the basic schedule in children. Rev. Saúde Pública [online]. 1995, vol.29, n.3, pp.208-214. ISSN 1518-8787.

Immunization coverage was evaluated in all 12-23 month-old children living in the area were five years before a Primary Care Practice had been set up. All children were investigated through home visits, checking of the immunization chart and relying on mothers' information. In 1986, a baseline study had identified an immunization coverage of under 60% for each of the scheduled vaccines. The current study confirmed that coverage was of 87% for three doses of DTP, 89% for Sabin, 88% for one dose of measles vaccine and 79% for BCG. Despite the high coverage achieved for each specific vaccine, when the basic schedule for the first year was verified, it was observed that only 75% of the children had received the full scheme. Immunization coverage is uneven in different census tracts, being higher in the poorest and more remot areas, where seam the health has given extra attention. A comparison with the routine administrative evaluation of the immunization coverage showed that this underestimated the real coverage. Maternal immunization uptake was also evaluated (antitetanus vaccine during pregnancy) and only 49% of the women were found to be adequately protected. The information collected led to a reorganization of the whole immunization program in a 100% coverage.
