Bangalore, While the Health Ministry may maintain that the incidence of cholera has seen a decline, experts feel otherwise. Hence, a new live oral cholera vaccine (IOCV) using recombinant technology will begin phase II clinical trial, this month. Funded and developed by the Department of Biotechnology, Ministry of Science and Technology, the phase II trial will be conducted on 60 volunteers at the National Institute of Cholera and Enteric Diseases (NICED), Kolkata. According to NICED director Dr G B Nair, it is the first attempt nationally to create a live oral vaccine.
