Dataset from Immunogenicity and Safety of a Booster Dose of GlaxoSmithKline Biologicals' IPV (PoliorixTM) in Healthy Chinese Toddlers

This study aims to evaluate the persistence of anti-poliovirus antibodies in toddlers aged 18 months who were primed with oral polio vaccine (OPV) or inactivated polio vaccine (IPV) in the primary study. The study will also assess the immunogenicity and reactogenicity of a booster dose of IPV in subjects primed with three doses of IPV.
