- The Department of Biotechnology (DBT) is to develop new influenza vaccines using a Controlled Human Infection Model (CHIM).
- Under CHIM, volunteers who take part in trials will be infected with infectious viruses or bacteria but under expert supervision.
- This approach will speed up the process whereby scientists can quantify whether potential vaccine candidates can be effective in people.
- It also identifies the factors that determine why some vaccinated people fall sick and others do not.
Objective
- To use CHIM protocols to study bacterial or enteric viruses (residing in the intestine) such as cholera or typhoid.
- If successful, these would serve to create back-ups to the existing cholera and typhoid vaccines.
