Antibodies from infected people were able to inhibit strains from both Asian and African lineages.
It's called antibody-dependent enhancement (ADE), wherein the dengue vaccine sets up severe disease in those not previously exposed — and it might have repercussions for Zika.
The study sheds light on how Zika antibodies bind to the virus. Also, Florida is investigating four possible local cases now, all from the same two counties: Broward and neighboring Miami-Dade.
Key findings in the monkey study were protection against later infection and that infections in pregnant animals lasted much longer.
Also, agencies publish guidance on Olympics travel and lab testing, and New York City officials outline their Zika response.
Inovio Pharmaceuticals will launch a phase 1 clinical trial of a DNA-based vaccine.
Also, a study found distinct temporal patterns between cases, GBS, and microcephaly.
As studies show more neuro problems, US officials urge full Zika funding.
Structure details may yield clues on how Zika damages cells and offer an inside track to drug, vaccine, and test developers.
The approach could be used to screen other dengue vaccine candidates, as well as for Zika vaccines.
