Official Title: Comparative Study of the Immunogenicity of MMR (Measles, Mumps and Rubella), Single Dose and Multidose Presentations in Children 12 to 23 Months of Age.
Brief Summary:
Whether the lower immunogenicity of the mumps component obtained in clinical studies with the MMR in Brazil, due to the multidose presentation. Investigations were made on factors that could interfere with immunogenicity of mumps component, as the kits used for the immunoassay method, and potency of the vaccine, but no explanation was found. This study aimed to investigate the hypothesis that the lower immunogenicity of the mumps component of the MMR Bio-Manguinhos vaccine, is due to the multidose presentation.
The Main objetctive is evaluate the immunogenicity of MMR after one dose in children 12 to 23 months of life, comparing the performances multidose vial (10 doses per vial of vaccine produced in Bio-Manguinhos/Fiocruz through technology transfer from GlaxoSmithKline Laboratory - GSK) and single dose vial (1 dose per vial of vaccine produced by GSK).
