Scientists Optimistic About Zika Vaccine After 'Striking' Results From Monkey Trial
The Associated Press: Zika Vaccines Work In Monkeys, Boosting Hopes For People
Three experimental Zika vaccines protected monkeys against infection from the virus, an encouraging sign as research moves into studies in people. The success in monkeys, which involved a traditional vaccine and two more cutting-edge ones, “brings us one step closer to a safe and effective Zika vaccine,” said Dr. Dan Barouch of Beth Israel Deaconess Medical Center in Boston. “But of course, there’s a lot more work to do.” (Ritter, 8/4)
Los Angeles Times: Three Vaccines Prevent Zika Infection In Monkeys; Vaccine Trial In Humans Gets Underway
The vaccines assessed by researchers from the Walter Reed Army Institute of Research, Harvard Medical School and elsewhere use three different methods to generate an immune response in patients. The first of them used a purified and inactivated version of the virus, which was too disabled to cause an infection but still caused the monkeys’ immune systems to make antibodies capable of fighting Zika. When deliberately exposed to the virus, none of the eight monkeys that received two doses of the vaccine showed any sign of infection. However, the eight monkeys that got the placebo became sick for about a week. (Kaplan, 8/4)
NBC News: 'Striking' Results From Early Zika Vaccine Trial
Three experimental vaccines being developed by researchers at Harvard's Beth Israel Hospital and the Walter Reed Army Institute of Research had already shown promise in mice — but monkeys are a much better model of how the medicines will work in humans. All three of the vaccines were found to be safe and protected the monkeys against infection with the virus, according to the report published in Science. (Carroll and Sarmiento, 8/4)
