The US began testing Zika vaccine on humans

US scientists on November 7 have begun testing a vaccine to prevent Zika virus in humans.

The Sify News website, which cited information from the Xinhua News Agency on November 7, said researchers at the Medical Testing Center at the Walter Reed Army Research Institute (WRAIR), Maryland, have been clinically tested. The human vaccine, the purified vaccine, is inactivated to prevent Zika virus from being prepared by the institute, called ZPIV .

This is the first stage of the five experimental phases conducted to assess the safety and prevention of Zika of this vaccine.

A total of 75 healthy volunteers participated in the vaccine test. Before being vaccinated with the Zika vaccine, volunteers were given one of the vaccines capable of boosting immunity to viruses similar to viruses that cause yellow fever or Japanese encephalitis.

The ZPIV vaccine contains a small amount of inactivated Zika virus , which means the virus cannot develop or cause disease in humans. However, the Zika virus protein shell remains the same, so when injected into the human body, the human immune system still recognizes and creates an immune response.

The next three phases of the Zika vaccine clinical trial will be conducted later this year at the University of St. Petersburg. Louis, Beth Israel Deaconess Medical Center and University of Health Sciences in Puerto Rico. This study is expected to be completed in the fall of 2018.

As expected, after completion of the trial phase, the new ZPIV vaccine will be included in the pilot program by the National Institutes of Health (NIH) in August 2017.
