Dengue vaccine first successful test in Bangladesh, effective on all four types

For the first time in Bangladesh, tests for dengue vaccine has been carried out successfully. Researchers of the International Centre for Diarrhoeal Disease Research (icddr,b) and the Vermont University's Larner College of Medicine in the US successfully completed these tests. News of this success appeared in the international journal Lancet on Wednesday.

This vaccine has been named TV-005 (Tetravelent). One of the icddr,b scientists involved in the research, Mohammad Shafiul Alam, speaking to Prothom Alo, said this is a hope-inspiring matter. With the extensive spread of dengue in the country, this is good news.

Mohammad Shafiul Alam said, a single dose of this vaccine can provide protection from dengue. But further research is required on this vaccine. The second phase trial has been carried out in Bangladesh. Various countries of the world have carried out trials in 42 different phases. The third phase trial has been carried out in India. There is huge possibility that this will protect people from dengue.

Scientist Shafiul Alam said, "We are also trying to carry out the third phase trial of the vaccine."
