A study has shown the mosquito protein AEG12 inhibits flaviviruses, the family of viruses that cause yellow fever, dengue and Zika.
Scientists show that an antibody targeting a protein acting as a viral toxin, can prevent the dengue virus from infecting human cells.
Researchers demonstrate that a subpopulation of circulating white blood cells can act as an early indicator of vaccine efficacy, with potential implications for COVID-19 drug development.
