How do the COVID-19 vaccines work?

Vaccination is a very safe way and one of the most effective ways of preventing (serious) disease and saving lives. When vaccinated, we not only protect ourselves but also our nearest and dearest and other people around us. When enough people are vaccinated, it becomes more difficult for the COVID-19 virus to spread, this is called group immunisation. Not everyone can be vaccinated (yet) - for example, babies, young children (<5 years), people with serious underlying conditions or certain allergies – so they are dependent on others who have been vaccinated to ensure that they are safe and cannot become seriously ill. In short, you get vaccinated to protect yourself, your loved ones, sick people unable to be vaccinated and our health care providers.
