HVTR IAVI Lab IndiaResearch scientists Nitin Hingankar and Huma Qureshi working on an HIV neutralizing assay at the HIV Vaccine Translational Research Laboratory in Faridabad, India

The HIV Vaccine Translational Research (HVTR) Laboratory at the Translational Health Science and Technology Institute (THSTI) was established as a joint initiative between the Department of Biotechnology, THSTI, and IAVI in 2012. The HVTR Laboratory studies the genetic and virological properties of circulating HIV strains in India, and complements the efforts of IAVI’s Neutralizing Antibody Center (NAC) to accelerate the development of broadly neutralizing antibodies (bnAbs) that would be affordable and applicable to low- and middle-income countries. It is part of the Indian government’s effort to create regional centers of scientific excellence to help address the burgeoning disease burden in the country.

The HVTR Laboratory comprises an interdisciplinary group of scientists with varied educational backgrounds and experience in virology, protein design and engineering, as well as antibody discovery and characterization. The team’s unique capabilities and multifaceted experience enable it to drive research in some of the most promising areas of antibody discovery and vaccine development. The HVTR Laboratory is playing a crucial role in spurring indigenous antibody discovery and preclinical development efforts, promoting industry collaboration on promising prevention products. It has also established strategic partnerships with leading academic and industry partners in India and across the globe.

The laboratory is funded by the Department of Biotechnology, Government of India; Department of Science and Technology, Government of India; Wellcome Trust-DBT India Alliance; Science & Engineering Research Board, Department of Science & Technology, Government of India; Research Council of Norway (GLOBVAC); and USAID via Microbicide and ADVANCE grants.

The HVTR Laboratory is based at the THSTI NCR Biotech Science Cluster in Faridabad, Haryana, India. The investigators at the HVTR Laboratory are:
