A Prospective, Open Label Study of Human T Cell Responses to Live Attenuated Japanese Encephalitis Vaccine SA14-14-2

Indian Institute of Science·interventional·Posted Aug 2, 2012·Updated Apr 26, 2019

In Brief

A Phase 4 clinical trial evaluating Live attenuated Japanese encephalitis vaccine SA14-14-2 for Japanese Encephalitis and Japanese Encephalitis Vaccine. Completed, enrolled 17 participants across 2 sites.

Detailed Summary

Japanese encephalitis (JE) live attenuated vaccine SA14-14-2 has been in use for more more than 20 years in Asia. JE vaccine SA14-14-2 is licensed in India and has been widely used since 2006. JE vaccines give protection by generating a neutralizing antibody response, but both naturally exposed persons and patients with JE also have T cell responses. Whether JE vaccine SA14-14-2 elicits T cell responses is unknown. This study tests the hypothesis that T cell responses are generated in response to JE SA14-14-2 vaccination. The aim of this study is to characterize T cell responses to JE vaccine SA14-14-2 in healthy people, and to investigate differences in T cell responses between natural exposure, vaccination and disease.
