What is a vaccine? Little Journey | NHS

Scientists have worked out a way to help our immune system fight off certain germs or viruses more quickly. These are called vaccines.

Having the coronavirus vaccine lets our immune system practice and learn how to destroy it. It doesn’t stop someone from catching coronavirus but it does mean that they won’t become very unwell if they do because their immune system is prepared and ready to fight it.

Little Journey have supported NHS Test and Trace to create accessible information for young people around coronavirus (COVID-19).

Thank you to all the children, families and NHS staff and researchers who have helped create these animations.
