(ABC News) Researchers are one step closer to creating an approved Zika vaccine, with the first round of safety trials already underway.
Drug companies have shown success in preclinical trials, in which they have induced immunity in mice and monkeys, indicating a greater likelihood that the vaccine could prevent infection in humans.
“In the last couple decades with modern microbiology, there’s been an explosion [in how quickly we] test vaccines,” Dr. William Schaffner, an infectious-diseases expert at Vanderbilt University Medical Center, told ABC News.
Two drug companies are leading the way in Phase 1 vaccine trials, which involve a small number of volunteers. In Phase 1 trials, researchers test the safety of a drug or treatment before testing for effectiveness in large groups. Inovio Pharmaceuticals and GeneOne Life Science paired up and dosed their first human subject last week.[Click the title, above, to post a comment.]
