It synchronizes data with the National Immunization Program Information System, thus enabling the maintenance of people’s vaccination history.

Objetivo: Analisar a completude do esquema vacinal contra hepatite B (recombinante) de adultos em município de Minas Gerais, segundo registros de imunização no Sistema de Informação do Programa Nacional de Imunização (SIPNI).
