Brazilian researchers say schistosomiasis vaccine could be available in 3 years

"Brazilian researchers say they have successfully tested a vaccine against schistosomiasis, a disease caused by parasitic worms that afflicts more than 200 million people worldwide," Agence France-Presse reports. Researchers from the Oswaldo Cruz Institute in Rio de Janeiro "said it had successfully tested the vaccine in humans, but that more testing would be required in areas where the parasite is most common, mainly in Africa and South America," the news agency writes. Institute researcher Tania Araujo-Jorge said she hopes the vaccine will be available for distribution within three years, according to AFP (6/13).
