ABSTRACT
<p><b>OBJECTIVE</b>In order to search the preparation process and optimazing dosage ratio of adsorbed diphtheria-tetanus-acellular pertussis and sabin inactivated poliovirus combined vaccine (DTaP-sIPV), the neutralizing antibody titers of IPV induced by different concentration of DTaP-sIPV were investigated on rats.</p><p><b>METHODS</b>Two batches of DTaP-sLPV were produced using different concentration of sIPV and the quality control was carried. Together with sabin-IPV and DTaP-wIPV ( boostrix-polio, GSK, Belgium) as control group, the DTaP-sIPV were administrated on three-dose schedule at 0, 1, 2 month on rats. Serum sample were collected 30 days after each dose and neutralizing antibody titers against three types poliovirus were determined using micro-neutralization test.</p><p><b>RESULTS</b>Two batches of prepared DTaP-sIPV and control sLPV were according to the requirement of Chinese Pharmacopoeia (Volume III, 2005 edition) and showed good stability. The seropositivity rates were 100% for sabin inactivated poliovirus antigen in all groups. The GMTs (Geometric mean titers) of neutralizing antibodies against three types poliovirus increased.</p><p><b>CONCLUSION</b>The prepared DTaP-sIPV was safe, stable and effective and could induced high level neutralizing antibody against poliovirus on rats.</p>
