Diphtheria is a highly contagious and potentially fatal infection that can affect the nose and throat, and sometimes the skin. It's rare in the UK but there's a small risk of catching it while travelling in some parts of the world.
Tetanus is a serious but rare condition caused by bacteria getting into a wound. If the bacteria enter the body through a wound, they can quickly multiply and release a toxin that affects the nerves, causing symptoms such as muscle stiffness and spasms.
The Polio virus attacks the nerves in the spine and base of the brain. This can cause paralysis, usually in the legs, that develops over hours or days. The paralysis isn't usually permanent, and movement will often slowly return over the next few weeks and months.
The teenage booster, also known as the 3-in-1 or the Td/IPV vaccine, is given to boost protection against 3 separate diseases: tetanus, diphtheria and polio. It's a single injection given into the muscle of the upper arm. It's routinely given at secondary school (in school Year 9) at the same time as the Men ACWY vaccine.
Your child will be invited to have the vaccination at school. If your child does not currently attend school, they will be invited to an alternative local community venue.
