Summer is synonymous with mosquitoes, and that means possible exposure to the West Nile and Zika viruses. Both are spread mainly through mosquito bites.
Researchers at Imperial College London have discovered compounds that can potentially prevent malaria parasites from infecting mosquitoes, which could in turn avoid the spread of the disease to humans.
Just one dose of an experimental Zika vaccine provided mice with 100 percent protection against a potentially lethal dose of the virus, researchers report.
