The information sheets on this page provide details on reaction rates of selected vaccines – whether single antigen or combined in a single product. WHO’s Immunization, Vaccines and Biologicals department has developed these sheets within its priority area supporting the introduction of vaccines in Member States.

The papers are primarily designed for use by national public health officials and immunization programme managers but may appeal to others interested in such information. Data from these sheets can be used for the evaluation of Adverse Events Following Immunization (AEFI) reported during national immunization programmes, but also for preparing communication materials about specific vaccines.

These information sheets include a short summary of the vaccine. They also comprise details of mild and severe adverse reactions (local and systemic) following immunization. Expected rates of vaccine reactions have been included if available in published literature.

Please find below a short guide on how to use the information sheets, as well as the current list of information sheets available.
