U.S. Develops World's First Vaccine for Chikungunya.

Updated on: 22-Dec-2016
US researchers have developed a vaccine for chikungunya fever made from an insect-specific virus that does not have any effect on people, making the vaccine safe and effective.

The study indicated that the vaccine quickly produces a strong immune defense and completely protects nonhuman primates from disease when exposed to the chikungunya virus. U.S. Develops World

Senior author Scott Weaver from the University of Texas Medical Branch at Galveston says,"This vaccine offers efficient, safe and affordable protection against chikungunya and builds the foundation for using viruses that only infect insects to develop vaccines against other insect-borne diseases".

Chikungunya is a mosquito-borne virus that causes a disease characterized by fever and severe joint pain, often in hands and feet and may include headache, muscle pain, joint swelling or rash. Some patients will feel better within a week but many develop longer-term joint pain that can last up to years. Death is rare but can occur.

Vaccine developed how quickly and safely the vaccine works.

Researchers used the Eilat virus as a vaccine since it only infects insects and has no impact on people.

They used an Eilat virus clone to design a hybrid virus-based vaccine containing chikungunya structural proteins.

The Eilat/Chikungunya vaccine was found to be structurally identical to natural chikungunya virus.

This study was published in journal of Nature Medicine.
