Abstract: Described are methods for inducing both a mucosal and a systemic immune response in the respiratory, digestive or urogenital tracts of a mammal to a microbial pathogen. The methods comprise topically administering onto the sublingual mucosa of the mammal an amount of an antigen effective to induce the mucosal and systemic immune responses and a pharmaceutically acceptable carrier or diluent. Pharmaceutical formulations and dosage forms for immunizing a mammal against a microbial pathogen to elicit a mucosal and systemic immune response in the respiratory, digestive or urogenital tracts are also described.

Abstract: This invention relates to the use of a specific carcinoma associated antigen/hapten of carbohydrate nature, fucosylsialosylgangliotetraose-IV.sup.2 -Fuc.alpha.-II.sup.3 NeuAc.alpha.-GgOse.sub.4 (Lipid Document, 1977) and defined derivatives, as well as to the use of antibodies against this antigen or its derivatives for body treatment procedures related to human cancer (exemplified by small cell carcinomas of the lung).
