Abstract:

Background: immunization is the most successful and cost effective public intervention. Immunization programs have led to eradication of smallpox, measles and poliomyelitis in region of the world and substantial reduction in the morbidity and mortality attributed to diphtheria tetanus and pertussis. The WHO estimates that 2 million child deaths were prevented bay vaccination in 2003, and also more deaths can be prevented by using currently existing vaccines.

Methodology: cross-sectional study was conducted at Ilemela at municipal council which located in Mwanza from June 2019 to July 2019. It included 350 mothers who have children between 18 and 24 months of age that were selected by convenient sampling. Data was filled and analysed by SPPSS Version 20

Results and discussion: this study coverage proportion of each vaccine was high except to some vaccines OPV- 0 and MR-2 which was 63.7% and 77.7% respectively, compared to other studies particular one which show that range of coverage in Tanzania was 80%-90% for standard vaccines (20).association between education level and vaccination coverage was strong in some vaccines such as BCG and MR-2 where by p value was found to be 0.01 and 0.003 respectively.

Conclusion and recommendation: coverage proportions of OPV- 0 nd MR-2 are still not satisfactory as compared to coverage estimate. Big emphasis should be put on insisting mothers to give birth at hospital so as to improve OPV- 0 coverage. Number of health care workers should be increased so as to reduce burden of work and improve the services provided at RCH clinics
