One issue in the dispute was that only the combined vaccine is available via NHS. Parents rejecting this vaccine can either pay for single vaccinations out of their own pockets or not vaccinate at all. Although Prime Minister Tony Blair publically defended the MMR vaccine, he refused to comment the vaccination status of his youngest son Leo at the same time.

The majority of pediatricians prefer the combined vaccine, as it is less strenuous for the child, and many parents rather have one vaccination done instead of three.

Epidemiological research on hundreds of thousands of children in numerous studies failed to indicate a link between MMR vaccination and autism. Critics of these studies, like the retired intern John Walker-Smith, although a supporter of the triple vaccine, labelled epidemiology a 'blunt tool' which does not necessarily expose such connections.<ref>http://www.vaccinationnews.com/DailyNews/February2002/AutBowMeas.htm</ref> As an example, it is difficult to find to populations differing in vaccination status only.

Dr.&nbsp;Wakefield gave up his position at the Royal Free Hospital in 2001 and now works for a controversial private hospital in the USA. His continued studies include research on possible immunological, metabolical, and pathological changes caused by "Autistic Enterocolitis", as well as connections between bowel diseases and neurological disorders in children and a possible connection between these disorders and influences like vaccines<ref>[http://www.thoughtfulhouse.org/bio_awakefield.htm A.&nbsp;Wakefield at his new employer]</ref>

In an article published 2011 in "health affairs" on the topic of vaccine opposition in the USA the authors (Kennedy et. al) come to the conclusion:

:''"Andrew Wakefield's report, which ran in the Lancet, may have been be "the flimsiest, most underpowered study supporting a conclusion of monumental importance to appear in a leading peer-reviewed journal in the past fifty years."''<ref>Kennedy A et al.

* In March 2005, a study on 30,000 children born in a district of Yokohama concluded that autism is on the rise (from 46-86 cases in 10,000 children to 97-161 cases in 10,000 children), despite the fact that MMR vaccines were no longer used in Japan since April 1993.
