Abstrakt: Recently, we developed and optimized a new method for the evaluation of the protective properties of serotype 2 inactivated poliovirus vaccines (IPV). The method is based on the immunization and subsequent challenge of transgenic (Tg) mice susceptible to poliovirus. We describe a similar method for the assessment of the protectiveness of serotype 1 IPV and demonstrate that experimental IPV produced from attenuated Sabin strain (sIPV) of serotype 1 poliovirus induced serum neutralizing antibodies, immunoglobulin (Ig) G, IgM, and salivary IgA at titers comparable to those induced by conventional IPV (cIPV) produced from the wild-type Mahoney strain. In contrast to our previous results with serotype 2 sIPV, serotype 1 sIPV provided even better protection of Tg mice than cIPV against challenge with wild-type Mahoney strain.
