Requirements for Haemorrhagic Fever with Rental Syndrome (HFRS) vaccine (inactivated), Annex 2, TRS No 848
Requirements for Biological Substances No 44

Overview
The development of inactivated HFRS vaccine in several countries has made it desirable to prepare international requirements for HFRS vaccine. The vaccine requirements presented here take into account the recommendations of a scientific group convened by WHO's regional office for the Western Pacific in 1989 to discuss the development of HFRS vaccines. Each of the following sections constitute a recommendation. To facilitate the international distribution of vaccine made in acoordance with these Requirements, a summary protocol for recording the results of tests is provided as Appendix 1. A general scheme for the preparation of HFRS vaccine is given as Appendix 2.
