Since 2009, WHO paid increasing attention to AEFI reporting. On the advice of the Global Advisory Committee on Vaccine Safety (GACVS), a set of 25 minimum core variables1 for AEFI reporting was developed for AEFI data collection, collation and transmission. These core variables help identify the minimum information to be gathered and also standardize meaningful AEFI data analysis. WHO has developed a standard WHO AEFI reporting form2 incorporating the core variables. Several countries have incorporated the core variables into their own AEFI reporting forms and AEFI data processing systems.
WHO encourages countries to develop and pursue electronic solutions of their AEFI data reporting using electronic tools and health management information systems (HMIS) platforms that are adapted to their local requirements. Vaccine Adverse Events Information Management Systems (VAEIMS) are being developed for pilot countries with WHO support illustrate the potential of information technologies (IT)-based systems to enhance the monitoring of vaccine safety concerns..
A recent VAEIMS version has been developed on a DHIS2 based platform. The DHIS2-based, VAEIMS version is also open source. This implies that countries will be able to access the “back end” of the software and make changes as per their local requirements without the need for a license. On specific country request, this DHIS2-based VAEIMS can be offered at nominal overheads for in-country use either as a stand-alone or as an integrated platform within the HMIS of a country.
VAEIMS information for action (VAEIMS – IFA) is an AEFI data processing and analysis training module that is built-in to this DHIS2 VAEIMS version. It is based on the 25 core variables and the WHO standard reporting form. It will help AEFI surveillance staff build capacity and skills in conducting online AEFI data analysis and training sessions. Using practical exercises, VAEIMS – IFA offers the learner practical step-by-step guidance in obtaining the correct data, knowing what to do with data obtained, assist in formulating a working hypothesis to facilitate and prioritize action.
The objective of VAEIMS is to facilitate the collection, collation, transmission, analysis and feedback of vaccine safety related data (AEFI data) from the periphery of the health care system, efficiently and effectively into a district, province and national database so as to provide information for action.
The objective of VAEIMS - IFA is to build capacity and skills among stakeholders in analyzing vaccine safety data and assist end users in
VAEIMS is installed in a central secure server or work station located at the ministry of health (MoH). For web-based versions, access to VAEIMS is granted only to authorized staff at national, province and district levels approved by the MoH. Access is granted through data base administrators at each level after specific approval process by the MoH.
At the grassroots level, the current prototype does not include a solution for the field level health worker, their supervisors and related field staff should be able to communicate minimum data (critical variables) to the district using mobile IT technology locally available. This will be developed only when the systems are in place for the higher levels and it is stable and running without any problems.
The end users of VAEIMS include (but are not restricted to)
VAEIMS Levels and privileges assigned to each level (proposed)
VAEIMS offers countries both online and offline options to report AEFI. It accepts all reports, including reports of vaccination errors.
Online AEFI reporting can be done by any person authorised by the ministry of health (MoH) to report an AEFI case. For online reporting, the user has to access the VAEIMS website and complete and submit the AEFI reporting form.
Offline AEFI reporting can be done by
Offline AEFI reporting can be done by
Personal identification data are not disclosed to the non-authorized VAEIMS users. Information identifying the person who received the vaccine and the person who filed the report is not made available to the public. Access to personal identification is only available to approved officials familiar with principles of privacy protection.
