Influence of several bacterial and viral vaccines on hepatic drug metabolism in mice.

ABSTRACT

Pentobarbital-induced sleeping time was found to be significantly prolonged in mice within at least 4 days following either whooping cough, tetanus, rubella or poliomyelitis vaccination. By contrast, barbital-induced sleeping time remained unaffected, These findings provide further evidence of a correlation between inhibition of liver drug metabolizing enzymes and stimulation of the immune response.
