PlaceboDRUGPlacebo for the Rotarix™ vaccine
Tritanrix-HepB/Meningitec conjugate vaccineBIOLOGICALThe full content of two monodose vials of Tritanrix-HepB vaccine vial was extracted and injected into the vial containing the lyophilized Meningitec (5/5/5) vaccine. The vial was agitated until the lyophilized vaccine pellet had completely dissolved. The reconstituted mixed vaccines were used promptly after reconstitution (within 30 minutes): one dose of 0.5 ml of the reconstituted Tritanrix- HepB/Meningitec vaccine was withdrawn from the vial and administered, the needle was changed before injection
Tritanrix/Hiberix vaccineBIOLOGICALThe full content of the Tritanrix-HepB vaccine vial was extracted and injected into the vial containing the lyophilized Hiberix vaccine. The vial was agitated until the lyophilized vaccine pellet had completely dissolved. The reconstituted mixed vaccines were used promptly after reconstitution (within 30 minutes): the full volume of the mixed vaccines was withdrawn from the vial, the needle was changed before injection.
