“Over the next decade, aided and abetted by useful idiots in the media, by British newspapers and other media that sensationalized the story, and the antivaccine movement, which hailed Wakefield as a hero, Wakefield managed to drive MMR vaccination rates in the U.K. below the level of herd immunity, from 93% to 75% (and as low as 50% in some parts of London). As a result Wakefield has been frequently sarcastically “thanked” for his leadership role in bringing the measles back to the U.K. to the point where, fourteen years after measles had been declared under control in the U.K., it was in 2008 declared endemic again.”
