Viruses are infectious micro-organisms that require something to attack/ be on to survive and multiply. When one enters your body, it invades and takes over cells, redirecting them to produce more of the virus. When our bodies come under attack from a viral infection they launch a defence known as 'the immune response'. Our immune system is designed to recognise the cells that make up our bodies and make sure invaders like viruses are killed
I wouldnt say a vaccine destroys a virus. it is supposed to give a small dosage of the virus so the immnune system fights it off and recongnises it in the future
