[The patterns of the corrective action of a natural immunomodulator on the secondary immunological defect caused by a corpuscular pertussis vaccine].

Purified staphylococcal toxoid (PST) was shown to be capable of preventing the development of secondary antigen-nonspecific immune deficiency in mice, immunized with whole-cell pertussis vaccine. The immunocorrective action of PST was manifested after its injection before (on day -1), simultaneously with and after (on day +1) the injection of whole-cell pertussis vaccine. Correction was either complete or partial, depending on the scheme of the experiment and the dose of PST.
