The Use of Gamma Radiation for the Preparation of Virus Vaccines
Suspensions of the viruses (mumps, influenza A (PR8), A/sub 1/ (FM/sub 1/ ), B, and swine influenza A) were irradiated in a Co/sup 60/ cell with a dose of 1.5 x 10/sup 6/ rad, which is about 50% higher thin the dose calculated to be required for inactivation. A protective agent such as histidine or Na p- aminohippurite was added to purified suspensions of influenzi and mumps viruses. It was then possible to inactivate them while retaining most of the hemagglutination titer. It was demonstrated in mice that a vaccine prepared from a mouse-adapted virus (Shope's swine influenza) conferred protection against challenge by the live virus and produced an antibody response as measured by the hemagglutinationinhibition technique. Vaccines prepared with the viruses of influenza A(PR8), influenza B, and mumps were shown to produce antibody responses in guinea pigs as measured by the hemigglutination-inhibition and serum neutralization techniques. The use of gamma irradiation has an advantage over most chemical procedures because its dosage of inactivation can be more accurately controlled. (H.H.D.)
