[Tetravalent diphtheria, tetanus, pertussis and inactivated poliomyelitis vaccine].

Two hundred forty-nine infants were immunized after being randomly allocated to the classical Tetracoq vaccine or to inactivated poliomyelitis vaccines prepared on monkey kidney cells or on Vero-type continuous cell lines either mixed with DPT or placed in a 2-compartment syringe separating (by-pass) the polio vaccine from the DPT. The 3 preparations were well tolerated and led to a good immune response: the first after 3 injections, the second and third after the second injection.
