The Zika outbreak of 2015 and 2016 is having lasting impacts on children whose mothers became infected with the virus while they were pregnant. Though the numbers of Zika virus infections have dropped, which scientists speculate may be due to herd immunity in some areas, there is still potential for future outbreaks. To prevent such outbreaks, scientists want to understand how the immune system recognizes Zika virus, in hopes of developing vaccines against it. Shannon Esswein, a graduate student, and Pamela Bjorkman, a professor, at the California Institute of Technology, have new insights on how the body’s antibodies attach to Zika virus. Esswein will present the work, which was published in PNAS, on Thursday, February 25 at the 65th Biophysical Society Annual Meeting.
