Singapore scientists crack 'sneak tactics' of dengue virus

Published on Jan 14, 2014 8:17 AM

Scientists in Singapore have discovered how the dengue virus manages to slip past the body's immune safeguards.

A team of researchers, led by Duke-NUS associate professor Ooi Eng Eong, believes its findings will help to develop a "more targeted" vaccine against the mosquito-borne virus.

There are four types of the dengue virus in Singapore and while catching one type makes you immune to that type, catching another type after that can cause even greater damage.

Typically, the body protects itself against repeat infections by producing antibodies, which latch on to viruses and mark them for destruction by white blood cells.
