Repurposed Drug Found to Be Effective Against Zika Virus
UC San Diego Health

In both cell cultures and mouse models, a drug used to treat Hepatitis C effectively protected and rescued neural cells infected by the Zika virus — and blocked transmission of the virus to mouse fetuses. Researchers at University of California San Diego School of Medicine, with colleagues in Brazil and elsewhere, say their findings support further investigation of using the repurposed drug as a potential treatment for Zika-infected adults, including pregnant women.

Zika Vaccine Induces Robust Immune Responses in Three Phase 1 Trials
Beth Israel Lahey Health

Healthy adults mounted strong immune responses after receiving an investigational whole inactivated Zika virus vaccine, according to interim analyses of three Phase 1, placebo-controlled, double-blind trials conducted at Beth Israel Deaconess Medical Center (BIDMC), Walter Reed Army Institute of Research (WRAIR), and Saint Louis University School of Medicine. The findings were published today in The Lancet.

Study Raises Possibility of Naturally Acquired Immunity Against Zika Virus
Cincinnati Children's Hospital Medical Center

Birth defects in babies born infected with Zika virus remain a major health concern. Now, scientists suggest the possibility that some women in high-risk Zika regions may already be protected and not know it. New research in PLOS Pathogens on Nov. 16, performed in mice, shows women who develop symptom-free Zika infections may be able to acquire immunity that would protect them from future infections and their offspring in a future pregnancy.

Antibody Protects Against Zika and Dengue, Mouse Study Shows
Washington University in St. Louis

The same countries hard hit by Zika virus – which can cause brain damage in babies infected before birth – are also home to dengue virus. Washington University School of Medicine in St. Louis researchers 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.

Test Uses Nanotechnology to Quickly Diagnose Zika Virus
Washington University in St. Louis

Currently, testing for Zika requires that a blood sample be refrigerated and shipped to a medical center or laboratory, delaying diagnosis and possible treatment. Now, Washington University in St. Louis researchers have developed a test that quickly can detect the presence of Zika virus in blood. Although the new proof-of-concept technology has yet to be produced for use in medical situations, test results can be determined in minutes, and the materials do not require refrigeration.
