13vPnC Multidose Vial Safety, Tolerability and Immunogenicity Study in Healthy Infants.
27. februar 2015 oppdatert av: Pfizer
A Phase 3, Randomized, Open-label Trial To Evaluate The Safety, Tolerability And Immunogenicity Of 13-valent Pneumococcal Conjugate Vaccine Formulated In Multidose Vials Given With Routine Pediatric Vaccinations In Healthy Infants
This study will compare the immune responses of the infants who have been given 13vPnC in the mutidose vial formulation to the immune reponses of the infants who have been given 13vPnC in the single-dose syringe formulation.
It will also evaluate the safety of 13-valent pneumococcal conjugate vaccine (13vPnC) in all infants who are vaccinated.
