Following the January 2011 BMJ statements of fraud by Wakefield, Paul Offit, a pediatrician at Children's Hospital of Philadelphia and a "long-time critic of the dangers of the anti-vaccine movement", said, "that paper killed children",[149][150][151] and Michael Smith of the University of Louisville, an "infectious diseases expert who has studied the autism controversy's effect on immunization rates", said "clearly, the results of this (Wakefield) study have had repercussions."[152][153] In 2014, Laurie Garrett, senior fellow at the Council on Foreign Relations, blamed "Wakefieldism" for an increase in the number of unvaccinated children in countries such as Australia and New Zealand, saying, "Our data suggests that where Wakefield's message has caught on, measles follows."[154]
