Most people have already had vaccinations for tetanus, diphtheria and polio, usually as a baby. These protected when you were small, but will now need topping up. Your 3-in-1 booster will help to increase this protection now that you are older.
You will also be offered the MenACWY vaccine, which protects against meningitis and related conditions.
Vaccination helps to protect you and those around you. Everyone in Year 9 will be offered the vaccinations at school.
It is important to have your vaccine at the right time. Please don't put yourself at risk by delaying.
