This study attempted to identify the barriers to reporting by the private sector. Methodology: The study was conducted in Kerala's Ernakulam district. The design of the study was cross- sectional. The end–users, who are from the private sector, were the participants of 28 in-depth interviews in the study. Results: The new reporting system has increased private sector involvement in information exchange, all 78 private hospitals (100%) were reporting to NHM Ernakulam. But the completeness of reporting was not uni- form. Major barriers identified were the lack of IIS interoperability with the hospital information system (HIS) being used by the private hospitals, variance because of lack of training of staff entering the data, and the una- vailability of dedicated staff for reporting data. Conclusion: Addressing these barriers could improve the reporting of routine vaccination data from the pri- vate sector.
