"Just five months after the Zika virus was declared a global public health emergency, a scientific team’s feverish efforts to create a vaccine against the viral threat have borne promising fruit: With a single shot of either of two different types of vaccine, experimental mice gained near-total immunity to Zika for at least two months.

Writing in the journal Nature on Tuesday, a U.S.-Brazilian team of scientists reported that two distinct vaccine candidates conferred powerful protection from Zika infection when each was delivered by intra-muscular injection to mice.

“We were very surprised — and quite impressed — that a single shot of either of these vaccines provided complete protection,” said study co-author Dr. Dan H. Barouch, who after years of work on vaccines against HIV pivoted in late January to work on Zika."
