Scientists have continuously been working to find ways of dealing with Zika virus, including the trial of vaccines on different animals.

Recently, scientists tried vaccines on monkeys, which gave hope of accessing Zika treatment. The researchers developed three experimental vaccines at Harvard’s Beth Israel Hospital in association with the Walter Reed Army Institute of Research. They tested them on monkeys. Prior to testing them on these species, the researchers tried the vaccines on mice.

However, when it comes to testing a treatment for humans, a monkey is a far better species than a mouse. When the vaccines were tested on monkeys, there was a ray of hope that maybe Zika’s effect on either newborns or adults could be mitigated.

With new updates coming into the scene relating to Zika virus and its transmission, it has become really important to get some ways of treating or preventing it. Researcher Dan Barouch claimed that non-human species are the best ones to try and experiment with the vaccines to judge their effectiveness.

“This gives us substantial optimism moving into human trials,” said Barouch. The scientists are led by the director of the Center for Boston’s Virology and Vaccine Research at Beth Israel Deaconess Medical Center. The details about the vaccines were published in the journal Science on Aug. 4.

The US National Institute of Allergy and Infectious Diseases (NIAID) mentioned that the vaccines are DNA-based. Hence, they contain Zika virus’ genetic remains. This will foster the immune response of the affected body against the infection. Health Day reported that almost 80 volunteers will receive the vaccine doses as per the schedule as part of the first phase of the clinical trial.

Earlier, it was assumed that the effect of Zika virus was only on newborn, who get the infection through their mothers. However, the latest study has revealed that the impact of the disease is similar in adults’ brains, which might lead to loss of memory and cognitive aspects.
