New Zika Vaccine: Testing in People Underway in US

A new vaccine against the Zika virus is being tested in people, and researchers said they hope to have early results by the end of the year, officials said today. Scientists have just started giving the vaccine to the first few volunteers as part of an early study run by the National Institute of Allergy and Infectious Diseases (NIAID). In total, 80 people in the U.S. ages 18 to 35 will receive the experimental vaccine during the trial.
