All the warning about the MMR vaccination turn into reality

5 Apr

A few years ago I used to regularly use the great UK MMR vaccination fiasco and the discredited work of  ‘Dr’ Andrew Wakefield as an example in my rational thinking classes. If you are interested in the whole MMR issue Ben Goldacre (as ever) has a very accessible summary. Over the last couple of years I’ve dropped it as a topic, as I rather naively assumed that with Wakefield work being so publicly discredited it was a piece of ‘history’ and not necessarily something that would engage students.

In recent months we’ve seen a very strange case of an Italian Court deciding that all the science is wrong, and now in the UK we have a major measles outbreak.

In the South Wales city of Swansea 588 measles cases have now been reported. This seems like both the ‘perfect’ ending for a new lecture on the MMR fiasco, and also a very good way to get students to think about complex ideas about what happens when ‘herd immunity’ drops. South Wales appears to be something of a blackspot for immunisation, with 1 in 6 children not vaccinated.

This graphic from America’s National Institute of Allergy and Infectious diseases is a nice introduction to the idea of ‘herd immunity’. I’ve also found this website which has a series of online simulations of various disease scenarios (including the ‘Swansea’ situation with a blackspot of low immunisation).

All things considered, the MMR lecture will definitely be making a comeback in October with an ‘all new’ section on herd immunity. As a postscript to this blog I’ve just searched for ‘Swansea measles’ on the Daily Mail website. The top three responses (see image below) are illuminating !

In ten years we seem to have ‘progressed’ from 75% of the public wanting an inquiry to ‘measles can kill’. If only we’d had more rational thinking in 2002 !!!
