Vaccines save millions of lives each year. Vaccines work by training and preparing the body’s natural defences – the immune system – to recognize and fight off the viruses and bacteria they target. After vaccination, if the body is later exposed to those disease-causing germs, the body is immediately ready to destroy them, preventing illness.
The covid-19 vaccine is very effective in preventing people from getting seriously ill or dying from COVID-19.
