The Zika virus is linked to brain damage in unborn babies and is spreading rapidly through South America. The World Health Organisation declared it an international emergency. Scientists are working on a vaccine and will soon want to test it on people. The Dilemma for students is: would you test a Zika vaccine? They review the science of cells and weigh up the risks and benefits by examining different sources (a revised version of our popular Ebola activity).
Cells: Make deductions about how medical treatments work based on cells, tissues, organs and systems (KS3 Science Syllabus)
Estimate risks: Weigh up the benefits and risks of an application of science to make a decision (KS3 Science Syllabus)
