PHS policy requires that institutions have an OLAW-approved Animal Welfare Assurance before performing any activities involving live vertebrate animals. One institution that receives PHS funds may rely upon another's Assurance to perform animal research if they do not have their own animal care and use program, facilities to house animals or an Institutional Animal Care and Use Committee.
The revised Interinstitutional Assurance guiudance clarifies essential information, lists institutional responsibilities, and defines required elements.
