title: Passive immunization for prevention of rotavirus illness in healthy infants.
abstract: Infant formula supplemented with bovine antibody (BCIg) to human rotavirus has been reported to prevent or modify rotavirus infection and illness. The purpose of this field trial was to determine the safety and feasibility of passive immunization with bovine antibody for the prevention of rotavirus infection and illness in healthy infants. Sixty-four infants, 31 of whom received BCIg and 33 placebo, participated in the study. Rotavirus infection was detected in 11 (35%) and 14 (42%) infants in the 2 groups, respectively. Symptomatic rotavirus infection was documented in 1 (3%) of the infants receiving BCIg and in 6 (18%) of the infants who received the placebo (P > 0.05). The number of days with diarrhea/1000 days of observation was significantly less in the BCIg group, 4.2, than in the placebo group, 16.8 (P < 0.01). Similarly the number of days with rotavirus-associated diarrhea/1000 days was less in the BCIg group, 1.0, than in the placebo group, 13 (P < 0.01). This study establishes the feasibility of providing passive immunity for the prevention of rotavirus illness in healthy infants.
