VACCINAL EFFICACY AUGMENTOR AND EFFICACY-AUGMENTING FOODS

摘要

A vaccinal efficacy augmentor comprises an IgA production promoter having an IgA production promoting effect as its effective component. The promoter is able to augment the efficacy of pathogenic virus vaccines. When administered with vaccines which contain bacteria or bacilli or virus antigens and which have the purpose of inducing immunity against infectious diseases, the IgA production promoter stimulates IgA producing cells such as Peyer's patch cells to promote secretory IgA production. Eventually, the production of an antibody against the antigen in the vaccine is augmented to well induce protective immunity and augment the efficacy of the vaccine. In addition, the augmentor can suppress side effects of the vaccine. The efficacy augmenting foods comprising the promoter
