  Purpose
To pilot test a mobile phone SMS system that will provide periodical messaging texts to mothers or custodians of infants who come for their first dose vaccines within the first 3 months of life to improve timely immunization coverage, vaccine acceptance and ensure vaccine safety monitoring. The intervention will include a "cloud-based" information system alimented by mobile phone data entry at the health post nurse level, that links child vaccination status and is able to remind parents and nurses of the need for next vaccination appointment and provide a system for reporting of adverse events following immunization in the immediate post-vaccination period.

Condition Phase
