Abstract: The present invention relates to immunogenic compositions comprising recombinantly constructed polypeptides useful for preparing vaccines, in particular for reducing one or more clinical signs caused by a rotavirus infection. More particular, the present invention is directed to an immunogenic composition containing (i) a fusion protein comprising in N- to C-terminal direction (A) an immunogenic fragment of a rotavirus VP8 protein and (B) an immunoglobulin Fc fragment such as, for example, an IgG Fc fragment, and (ii) an immunogenic substance, different from said fusion protein, wherein said immunogenic composition is usable in a method of reducing one or more clinical signs, mortality or fecal shedding caused by a rotavirus infection in swine.
