Live attenuated dengue vaccine development: Experience of Mahidol University

Development of an Attenuated Live Virus Vaccine against Sheep Pox

Genetically modified, live attenuated dengue virus type 3 vaccine candidates.

Three novel recombinant dengue type 3 (DEN3) virus vaccine candidates have been generated from a DEN3 virus isolated from a mild outbreak of dengue fever in the Sleman area of central Java in Indonesia in 1978. Antigenic chimeric viruses were prepared by replacing the membrane precursor and envelope (ME) proteins of recombinant DEN4 (rDEN4) virus with those from DEN3 Sleman/78 in the presence (...

A Promising, Single-Dose, Live Attenuated Tetravalent Dengue Vaccine Candidate.

Dengue virus (DENV) represents a rapidly expanding global health threat, with approximately 40% of the world’s population now living in >100 countries at risk for DENV transmission, including the United States [1, 2]. In 2010, an estimated 390 million DENV infections occurred worldwide, of which 96 million were symptomatic [3]. DENV infections produce a spectrum of clinical disease. This includ...

Development of a New Live Attenuated Mumps Virus Vaccine in Human Deploid Cells

Vaccination of human volunteers with monovalent and tetravalent live-attenuated dengue vaccine candidates.

Four serotypes of monovalent live attenuated dengue virus vaccine candidates were tested for reactogenicity and immunogenicity in 49 flavivirus non-immune adult human volunteers. The four monovalent candidates were then combined into a tetravalent formulation and given to another 10 volunteers. Neutralizing antibody seroconversion rates after a single-dose monovalent vaccination ranged from 53%...
