title: [Oral vaccination with live attenuated rotavirus].
abstract: A randomized, double-blind trial was performed to assess serological response and clinical protection for acute gastroenteritis due to rotavirus in 103 children aged 6 to 18 months, after a single dose of RIT 4237 live attenuated bovine rotavirus vaccine or placebo. Seroconversion, determined by enzyme-linked immunoabsorbent assay (ELISA), was significantly greater in initially seronegative vaccines compared with control group (p less than 0.0001); clinical protection rate was low in this study group and it is therefore concluded that seroconversion by itself is not sufficient to measure vaccine efficacy.
