Clinical evaluation of a single oral dose of human-bovine (UK) reassortant rotavirus vaccines Wa x UK (P1A[8],G6) and Wa x (DS-1 x UK) (P1A[8],G2).
The safety, infectivity, and immunogenicity of two human-bovine reassortant rotavirus candidate vaccines were evaluated in adults, children, and infants. One of these, Wa x UK, contained a single human rotavirus gene from the Wa strain that encoded VP4 P1A specificity in a background of 10 bovine genes including the VP7 gene that encodes G6 specificity, whereas the other, Wa x (DS-1 x UK), possessed the human rotavirus VP4 gene from the Wa strain as well as the human VP7 gene from strain DS-1 that encoded G2 specificity. Each of these vaccines appeared to be well-tolerated and immunogenic in infants less than 6 months of age following a single oral dose, and therefore should be evaluated further as vaccine candidates.
