title: Local and systemic antibody response to rotavirus WC3 vaccine in adult volunteers.
abstract: An evaluation of the safety and immunogenicity of WC3 rotavirus vaccine was evaluated in adult volunteers. Pre- and post-vaccination titers of neutralizing antibody to WC3 and to the four human rotavirus serotypes as well as serum and stool rotavirus IgA levels were measured. Vaccination was safe and did not induce elevation of liver enzymes. None of the 12 volunteers receiving WC3 vaccine shed detectable amounts of virus although antibody rises were detected in 11 of 12 vaccines. Nine developed and increase in WC3 neutralizing antibody, one additional subject had a rise in Wa (human serotype 1) neutralizing antibody while another subject only developed a rise in stool rotavirus IgA. All of the vaccine recipients with a rise in WC3 neutralizing antibody also developed a rise in neutralizing antibody against at least one of the four most common human rotavirus serotypes. A stool IgA rotavirus antibody response was detected in 6 of 9 WC3 recipients with measurable stool antibody. None of the control subjects developed significant rises in any of the antibody titers measured. WC3 rotavirus vaccine appears to be safe and induces systemic and local immune responses in adults suggesting that further evaluation of WC3 should be considered in infants.
