Vaccinations & Immunisation

• Vaccine


  Exposes the body to weakened or inactivated pathogens, allowing the immune system to develop immunity without causing the full disease
• Vaccines


  • Contain weakened or inactivated pathogens that the body recognizes and responds to by producing antibodies, developing immunity
  • Protect against catching horrible diseases
  • Help control and prevent outbreaks of diseases that used to be common, like polio, smallpox, measles, whooping cough
• Herd immunity


  When enough people in a population are immune to a pathogen, the pathogen has no one to spread to and disappears
• Vaccines don't always work

  Sometimes they don't grant full immunity
• Vaccines


  Can sometimes cause bad reactions like swelling, fevers, or seizures, but these are rare
• The pros of vaccines generally outweigh the cons
