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 mice and nonhuman primates from disease when exposed to the chikungunya virus.
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.
