Since Canada started vaccinating against measles, there was a more than tenfold decrease of measles incidence (De Serres et al., 2013). However, there were several outbreaks reported in Canada from 2008-2011, ranging from 56 to 30,000 cases. Currently, the major cause of measles outbreaks is failure to vaccinate or incomplete vaccination (Dallaire, De Serres, Tremblay, Markowski & Tipples, 2009; De Serres et al., 2013; De Serres, 2012; Duclos, Redd, Varughese, & Hersh, 1999). Other causes of measles infection include travelling to countries with lower rates of vaccination (Bird, 2013). As citizens of multicultural country, Canadians are particularly susceptible to the spread of infections that circulate around the world.

After release of his work, numerous studies were done to investigate whether there is any link between MMR vaccine administration and autism. The studies with varying numbers of participants showed that there is no evident link between those two events (Uchiyama, Kurosawa, & Inaba, 2007; Purssell, 2014). However, a Danish national investigation showed that there was an overall increase in the number of cases of autism since the introduction of MMR vaccine, from 8.38 to 71.43 cases per 100 000 children (Goldman, & Yazbak, 2004). The increase in autism diagnosis since introduction of MMR vaccine can be explained by such determinants of health as health care, environment, healthy child development and genetic endowment. For instance, there might have been an increased recognition of a disease such as autism, and less severe cases began being diagnosed more commonly. Also, there might have been some environmental changes in the country where the study was carried out which could result in growth and developmental delay of the
