Millions are rejecting one of humanity’s best weapons for saving lives: Vaccines
Vaccines show the immune system what the virus looks like so our bodies can manufacture specific antibodies to that virus. These antibodies then bind to and inactivate or destroy invading viruses.
Working with dangerous viruses sounds like trouble – but here’s what scientists learn from studying pathogens in secure labs
There is no such thing as zero risks in any endeavour, but over many years, researchers have developed safe laboratory methods for working with dangerous pathogens.
How virus detectives trace the origins of an outbreak – and why it's so tricky
Plant, animal or human, the methods are largely the same. Tracking down the origins of a virus involves a combination of extensive fieldwork, thorough lab testing and quite a bit of luck.
Engineered viruses can fight the rise of antibiotic-resistant bacteria
Viruses may be be the heroes of the next epidemic rather than the villains. Scientists have shown that viruses could be great weapons against bacteria that are resistant to antibiotics.
