[Reactogenicity associated to the intradermally administered inactivated poliovirus vaccine with a needle-free injector].

Introduction: As the goal of poliomyelitis eradication is about to be accomplished, the need for an affordable and appropriate inactivated poliovirus vaccine (IPV) for use in developing countries has become a target for WHO.

Objective: To evaluate the reactogenicity of the inactivated poliovirus vaccine.
