Childhood vaccine status and correlation with common nonvaccine‐preventable illnesses
A current trend however is numerous parental refusals of vaccinations for their children or requests for partial administration (Connors et al., 2012; Gust, Darling, Kennedy, & Schwartz, 2008; Yaqub, Castle‐Clarke, Sevdalis, & Chataway, 2014). One of the prevalent parental reasons for this decision relates to their perceived uncertainty about both short‐term and long‐term immune system effects with the large volume of vaccines administered (Bakhache et al., 2013; Byström, Lindstrand, Likhite, Butler, & Emmelin, 2014). This perceived uncertainty has led to an ever increasing group of people making alternative choices to the immunization schedule and in some cases choosing to not vaccinate their children at all. With this trend we have seen the reoccurrence of what were previously considered eradicated diseases, such as measles. Previous studies have looked at barriers to vaccination and Byström et al. (2014) found that parents highlighted the need for vaccine information from sources unbiased from pharmalogical company influence. Some parents have unsubstantiated concerns about the effect of multiple immunizations on their children's immune system. These parents have concerns that it could make their children more susceptible to childhood illnesses. There is little research about the effect of immunizations on other childhood illnesses. The purpose of this study is to determine if there is a difference in incidence of common childhood illnesses dependent on vaccination status.
