[NIH potency tests with inactivated rabies vaccines (author's transl)].

Abstract

63 NIH tests were analysed. A BPL inactivated tissue culture rabies vaccine No. 108 was compared with the national standard vaccine A 18 fourteen times in different tests. The results show that reproduction of results is unsatisfactory with the NIH test and that this test in its present traditional method with two injections is not very suitable for satisfactory potency evaluation of inactivated rabies vaccines. Proposals for modifications are made.
