Eric In the UK, scientists are testing a new vaccine. The vaccine is for melanoma. Melanoma is skin cancer. It is very dangerous. It kills thousands of people every year.
This vaccine is special. It is different for every person. It works with the immune system. It helps the body find and fight dangerous cells.
Similar tests are happening in Australia and other countries too. People hope that it will work. It may stop cancer from coming back. If it works, it can save people in the world.
Difficult words: cancer (a dangerous disease when a part of the body starts to grow without control), immune system (organs and substances in the body which make the body strong), cell (the smallest part of a living organism).
