Vaccination

8 Internet researches into vaccination issues

Conclude your study by undertaking some broad Internet searches on key topics raised in this course. First, bring yourself up to date with the current status of the MMR debate. Spend about one hour on this exercise.

Activity 30

You will certainly find a number of sites with highly polarised opinions in the MMR debate. You should aim to evaluate the reliability of the sites you visit. What evidence do they present? Do they reference their evidence? How much use is made of quotations from individuals? What links do the websites provide? Are links to other sites selective to one side of the debate, or do they address the other side too? Here are some of the other questions that you might consider:

  • Has a fall in the uptake of MMR in any country been associated with an increase in the incidence of measles, or mumps, or rubella? Is it possible to quantify the effect?

  • What evidence has emerged either to support or contradict concerns about a link between MMR and autism or other adverse outcomes?

  • What are the effects of measles in unvaccinated children in developing countries?

  • Have concerns been expressed about possible adverse outcomes of any other vaccine, and (if so) on what evidence has this been based?

Activity 31

Now investigate the details of at least one other vaccination programme (in addition to the polio eradication campaign, which you should already have researched as part of the Polio Case Study). Spend about one hour on this exercise.

  • Identify the type of vaccine used, the method of delivery and any issues that have emerged during the organisation of the programme.

  • What has been the effect over time on the incidence or severity of the disease? How has this varied in different locations?

  • What are the prospects for eradicating the infectious agent globally through mass vaccination programmes? What factors are delaying or threatening progress?

We have provided some links below to websites dedicated to vaccination data and progress reports in the UK, USA and internationally, but there are many others.
