A Quebec City-based research team has received the green light to begin testing a Zika vaccine on humans in collaboration with U.S.-based partners. The researchers based at Universite Laval are the first in Canada to be authorized by Canada's federal health agency and the U.S. Food and Drug Administration to conduct clinical tests. The university is one of three sites that hope to begin testing a vaccine for the mosquito-borne virus in the next few days. (7/20)

Florida health officials have trapped mosquitoes in an area of Miami-Dade County and are testing them for Zika to confirm whether a woman with the virus could be the first person infected directly by a mosquito bite in the continental United States.
