Vaccinations

• A vaccination is a method of artificially inducing immunity so that we can become immune to a pathogen without getting ill.
• If you are vaccinated then you are less likely to catch the disease as the vaccination has given you immunity against it.
• Vaccinating a large population means the disease is less likely to spread as almost everyone is immune.
• 3 drawbacks of vaccinations:

  • Don't always give full immunity
  • can cause mild symptoms
  • could in very rare cases cause severe reactions(seizures)
