I/GCSE Biology: Vaccination Programmes

Vaccinations

· vaccination,biology,Immunity,igcse biology

Do you guys still remember vaccination programmes in I/GCSE Biology?

Immunization Programs

  • Protect against diseases common in children
  • E.g. MMR (combination of Measles, Mumps and Rubella), gain immunity to this
  • Have saved millions of children’s lives
  • Enough people immunised =more difficult for virus to pass onto those who aren’t, carrier mostly comes into contact with immunised people
  • 90% of population immunised = prevent epidemic

Concern about vaccines

  • Unvaccinated children = likely to develop serious disease
  • Whooping cough = long bouts of coughing/choking – hard to breath #
  • Whooping cough can kill babies under 1
  • Major outbreak = parents concerned on side effects

The MMR controversy

In I/GCSE Biology,

  • MMR might trigger autism - Study based on 12 children
  • In UK children receiving MMR dropped by 60% (2005), MMR jabs received raised to 98% (2010)
  • No more studies have linked MMR and autism after that
  • Parents think of children, government think of society as a whole

That's all~
