Curious Kids: how do vaccines kill viruses?

Vaccines work by teaching your immune system about new viruses. Your immune cells are very clever – they will remember what they learnt, and protect you if you encounter that virus in the future.

One small part of a human antibody has the potential to work as a drug for both prevention and therapy of COVID-19

Antibodies are great for neutralizing viruses. But they are big and bulky. Antibody engineers are now creating smaller synthetic antibody-like molecules that may be better for fighting COVID-19.
