17D Yellow Fever Virus Vaccine
Dear Sir: In a recent article, Edupuganti and others reported a clinical study of co-administration of subcutaneous yellow fever (YF) 17D vaccine (YF-VAX Ò ; Sanofi Pasteur, Lyon, France) and intramuscular immune serum globulin (ISG) (amaSTAN S/D Ò ; Talecris Biotherapeutics, Research Triangle Park, NC) or saline placebo. 1 The study was designed to test whether co-administration of vaccine and...
متن کاملImmunogenicity of WHO-17D and Brazilian 17DD yellow fever vaccines: a randomized trial.
OBJECTIVE To compare the immunogenicity of three yellow fever vaccines from WHO-17D and Brazilian 17DD substrains (different seed-lots). METHODS An equivalence trial was carried out involving 1,087 adults in Rio de Janeiro. Vaccines produced by Bio-Manguinhos, Fiocruz (Rio de Janeiro, Brazil) were administered following standardized procedures adapted to allow blocked randomized allocation of...
متن کاملAttenuation and immunogenicity of recombinant yellow fever 17D-dengue type 2 virus for rhesus monkeys.
A chimeric yellow fever (YF)-dengue serotype 2 (dengue 2) virus was constructed by replacing the premembrane and envelope genes of the YF 17D virus with those from dengue 2 virus strains of Southeast Asian genotype. The virus grew to high titers in Vero cells and, after passage 2, was used for immunogenicity and attenuation studies in rhesus monkeys. Subcutaneous immunization of naive rhesus mo...
متن کاملLimited replication of yellow fever 17DD and 17D-Dengue recombinant viruses in rhesus monkeys.
For the development of safe live attenuated flavivirus vaccines one of the main properties to be established is viral replication. We have used real-time reverse transcriptase-polymerase chain reaction and virus titration by plaque assay to determine the replication of yellow fever 17DD virus (YFV 17DD) and recombinant yellow fever 17D viruses expressing envelope proteins of dengue virus seroty...
متن کاملThe phylogeny of yellow fever virus 17D vaccines.
In recent years the safety of the yellow fever live vaccine 17D came under scrutiny. The focus was on serious adverse events after vaccinations that resemble a wild type infection with yellow fever and whose reasons are still not known. Also the exact mechanism of attenuation of the vaccine remains unknown to this day. In this context, the standards of safety and surveillance in vaccine product...
