The final straw came with the row over the MMR vaccine. Scientists maintained that the vaccine was safe, while one of their own - Andrew Wakefield at the Royal Free Hospital - argued that there was, in fact, a connection between the triple vaccine and autism. Britons went to the barricades. There are more parents than farmers, more children than Prozac consumers. MMR whipped into a fury the concerns that hitherto had merely raised temperatures. The controversial jab prompted people to question everything from the scientists' motives to their procedures.
