Antibody protects against Zika and dengue, mouse study shows

The same countries hard hit by Zika virus — which can cause brain damage in babies infected before birth — are also home to dengue virus. Researchers now report that they have found an antibody that protects against both viruses. These findings, in mice, could be a step towards an antibody-based preventative drug to protect fetuses from brain damage, while also protecting their mothers from both Zika and dengue disease.
