VCS: An open source Web-based vaccination management information system

This work presents VCS (Vaccination Control System), a Web based application implemented using the PHP script language, the PostgesSQL DBMS and the Apache web server under a GNU/Linux platform. VCS is a management information system tool for the vaccination process control, which was modelled and designed towards the necessities of the Brazilian public health system. The current version of VCS includes the management of vaccines, patients, mass immunization campaigns, access control to the recorded information, record of immunizations and history of immunizations per individual, and many statistical reports. An important social benefit provided by VCS is the improvement in the strategic planning for the public vaccination system, which results in a better assistance to the population in general and resources savings by governments with the reduction of vaccine lost.
