Operational challenges such as logistic supply and microplanning have to be taken into consideration There is also increasing need to ensure that providers stick to service delivery protocols to achieve better health outcomes. Therefore the Study was aimed to assess the immunization sessions. The objective of the study was to evaluate the immunization sessions for logistics and availability of health workers, in the study area.Methods: The study was carried in 21 Grampanchayats covered by Ghatnadur PHC. semi structured preformed questionnaire was used for evaluation. Immunization sessions were also studied for information provided regarding side effects of vaccines.Results: Availability of human resources and logistics for vaccination sessions was more than 80% at all vaccination sessions. Information about side effects was the loophole in vaccine delivery services. Message regarding side effects of vaccines was not conveyed to most of the population.Conclusions: Vaccine delivery services were good in study area.
