India's Indigenous Dengue Vaccine in Trials

India is testing a new vaccine called DengiAll to prevent dengue fever.

This vaccine is special because it's a single shot that works against all four types of dengue virus.

Unlike other vaccines, it's designed to work in real-world conditions, which is important because dengue is a tricky disease.

The vaccine aims to protect people from all strains of the virus at once.

This is a big deal because past vaccines have only worked against one strain, and getting infected with one strain can sometimes make you more vulnerable to others.

The vaccine is being tested in Delhi, and if it works, it could help India and other countries prevent dengue outbreaks instead of just treating them.

However, there are still challenges, like making sure the vaccine is safe and effective for everyone, and dealing with the changing patterns of mosquito-borne diseases due to climate change.
