There are three reasons why we immunise children.
- First, immunisation prevents **** from becoming ill with unpleasant and serious infectious ****, which have a risk of complications and long-term side effects.
- Second, we immunise to try and help protect all **** in the population. The more people who are immunised, the less of the infectious ** there is around so the less chance there is of anyone catching it. When levels of immunisation against an infectious ** are really, really high - then something happens called 'herd immunity' where the risk of the *** occurring is so low that even those who cannot be immunised are unlikely to be affected.
- Third, we immunise to try and wipe out as many infectious **** as we can everywhere in the world.
