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.
