Several nations have started vaccinating their citizens – but the coronavirus is far from beaten – which means detecting the virus is still a prime objective. Testing is key to beating COVID-19.

A person’s antibodies can show us who has some immunity to the virus, so lockdowns can be lifted, and people can get back to work.

A German entrepreneur and scientist has been developing ways to not only test many people quickly, cheaply and to stop chains of infection – but to also enable folks to go on with their lives.
