Abstract
Inducers of non-specific immunity are obtained by increasing the pH of a virus suspension of viruses which elicit non-specific immunity and then heating the pH-increased virus suspension. The pH value can be increased to between about 8 and 11 and heating is carried at temperature between about 50.degree.-60.degree. C.
Claims9
A process for the preparation of an inducer of non-specific immunity comprising inactivating a virus suspension of avipox viruses, parapoxviruses, paramyxoviruses, reoviruses, or inactivated virus suspension obtained from the inactivation process according to claim 1.
An inducer of non-specific immunity, which is the herpesviruses by increasing the pH of the virus suspension to a pH between about 8 and 11 and thereafter heating said pH-increased virus suspension at a temperature between about 50.degree. to 60.degree. C. for a period between about 40 to 120 minutes thereby inactivate the virus, and lower antigenicity, but without destroying non-specific immunizing activity.
