Deaths among under 5 children from measles and its complication is the major killer worldwide. As per 2017 global coverage of measles is 89% and pentavalent (diphtheria, pertussis, tetanus) its 85%. Still 71 countries have yet to achieve global vaccine action plan (GVAP) target of 90% coverage of 3 doses of DTP. India is one among these countries with only 63.9% coverage, and the state of Telangana has coverage of 67.5% according to National family health survey-4 (NFHS-4) (2015-2016).Methods: A community based cross sectional study was conducted among 12-24 months age children, sample size of 199 is calculated by using the formula of 4pq/l2 and by considering the immunization coverage of 66.7% according to the NFHS-4 (2015-2016) of Telangana state and allowable absolute error of 7% and nonresponsive rate of 10%, simple random sampling technique was used and data collected by using semi-structured questionnaire, data was analysed using MS-office and OpenEpi.Results: Among 199 study population 136 children were Hindus and 53 were Muslims and 10 from other religion. Mean age and standard deviation of study population was 14±4.56. Among total population 72.9% (145) are completely immunized, 25% (50) are partially immunized 2.04% (4) are unimmunized.Conclusion: Immunization coverage was higher in the present study then the state of Telangana i.e., 67.5% as per NFHS-4.the rural population.
