FOX NEWS — CHICAGO – Mice given a single shot of one of two experimental Zika vaccines were completely protected when exposed to the virus one to two months later, a promising sign that similar vaccines under development for humans will protect against Zika, U.S. researchers said on Tuesday.
“This is an encouraging first step in Zika vaccine design and pre-clinical testing. This new mouse model should be useful for comparative assessments of the large range of vaccine candidates now being designed,” said Professor Adrian Hill, director of Oxford University’s Jenner Institute, which did not conduct the mouse study but is also developing Zika vaccines.
Separately, U.S. scientists said they have developed a model of the Zika virus in monkeys, a close proxy for human disease.
The studies advance efforts in fighting the mosquito-borne Zika virus, which has swept through the Americas and Caribbean since last fall, and has been linked to thousands of cases of microcephaly, a rare birth defect, in Brazil, as well as to neurological disorders. On Feb. 1, the World Health Organization declared Zika a global health emergency.
