US Scientists Testing Zika Virus Vaccine
U.S. scientists are testing a Zika virus vaccine. The experimental vaccine is called the Zika Purified Inactivated Virus (ZPIV) vaccine.
The human trials have begun at the Walter Reed Army Institute of Research (WRAIR) Clinical Trial Center in Silver Spring, Maryland. Researchers will recruit seventy-five adults to participate in the trials.
The technology is the same that was used to create a vaccine for another virus, which was licensed in 2009. NIH says the ZPIV vaccine contains whole Zika virus particles that have been inactivated, meaning that the virus cannot replicate and cause disease in humans. The protein shell of the inactivated virus remains intact so it can be recognized by the immune system and cause an immune response.
The study is expected to be completed by fall 2018.
