Three important antigenic sites involved in virus neutralization on
polioviruses in mouse experiments have been identified. These sites are
located at the surface of the virion and have been designated antigenic
sites 1, 2, and 3. In mice, the antibody response to antigenic site 1 of serotype 3 poliovirus is considered to be immunodominant, but little
is known about the immunogenicity of these sites in humans. In the
present study, we developed inhibition enzyme-linked immunosorbent
assays specific for antigenic sites 1 and 3 to measure antibody
responses to these sites in fully vaccinated inactivated poliovirus
vaccine (IPV) (n = 63) and oral live attenuated
poliovirus vaccine (OPV) (n = 63) recipients and in
naturally infected persons (n = 25). Similar levels of
antibodies to site 1 in IPV and OPV vaccinees were detected. However,
significantly more OPV recipients (88.7%) had detectable antibodies to
antigenic site 3 (P < 0.01) than did IPV-vaccinated
persons (63.1%). After an IPV booster vaccination, both previously
IPV- and OPV-vaccinated persons responded with a significant increase
in antibodies to sites 1 and 3 (P < 0.01). We
conclude that the immune response to serotype 3 poliovirus in humans
consists of both site 1- and site 3-specific antibodies and that these
responses can be induced by either OPV or recent IPV vaccination.
