Requirements for measles, mumps and rubella vaccines and combined vaccine (live), Annex 3, TRS No 840
Requirements for Biological Substances No. 47

Overview
Combined live vaccine for measles, mumps and rubella (MMR) is used widely for immunization of children in certain regions of the world because of its advantage over the individual vaccines.
The last revision of the Requirements for Measles vaccine (Live) was adopted by the WHO ECBS in 1987. In that revision, account was taken of the opinions of consultants, of the regulations and requirements for the manufacture and control of measles vaccine that has been formulated in number of countries, and of information from published and unpublished sources. For the present revised Requirements, published together with the new Requirements for Combined Vaccine, some changes have been made to the previous revision.
The Requirements for Mumps Vaccine (Live) were adopted by the WHO ECBS in 1987, and have been included in this combined document with some changes.
The Requirements for Rubella Vaccine (Live) were adopted by the WHO ECBS in 1977, with an addendum in 1990, and have been included in this combined document with some changes.
