Immunologic characteristics of a polyvalent vaccine

: A lot of bacterial vaccines show a very interesting immunostimulating profile. The AA. studied the effects of a polyvalent vaccine on the phagocytosis, on the cellular immunity and on the IgA production. They also investigated its capacity to reactivate the response to the C tetani toxin (Booster effect), both "in vitro" and in human volunteers. The results show a significant improvement in the immunity response to specific and aspecific stimuli.
