The current DHIS2 Gambia Health Information system is only capturing the aggregated data for vaccine consumption but is not capturing the child information per antigen. I have started using dhis2 since 2010 and i have lot of internal training on DHIS2. I develop an excel database in 2005 when i was posted in the regional level as Data Entry clerk.
