      Lesson details

      Learning outcome

      I can explain the benefits of immunisation and evaluate the arguments around them.

      Key learning points

      1. Vaccines protect against deadly diseases.
      2. Vaccines are thoroughly tested before being used.
      3. Vaccines do not contain anything harmful, only ingredients to make them work.
      4. Vaccines have made deadly diseases like smallpox, polio and tetanus, rare or eliminated in the UK.
      5. If people stop having vaccines, it's possible for infectious diseases to quickly spread again.

      Keywords

      • Immunisation - the process of becoming immune or resistant to a disease, usually through a vaccine

      • Vaccination - the process of receiving a vaccine, for example, receiving the injection, or taking an oral or nasal dose

      • Antibodies - disease-fighting proteins that play a crucial role in the immune system; they recognise infectious invaders, such as bacteria and viruses, and help the body destroy them

      • Live vaccines - contain weakened versions of viruses or bacteria, giving long-term protection

      • Non-live vaccines - contain viruses or bacteria that have been destroyed, or just parts of them; several doses or a booster are needed for full protection

      Common misconception

      You only have vaccinations as a baby or young child.

      Vaccinations are offered by health professionals at different ages.

      Teacher tip

      You may wish to work with your local public health team to time delivering this lesson at the same time that pupils might receive vaccinations.
