Exploring the Association between Parental Concern about Vaccine Safety and Incomplete Childhood Immunization: A Multivariate Model
DownloadSpring 2013
High levels of immunization coverage are required to maintain control of infectious diseases that previously caused significant illness and death in Canada. However, childhood immunizations have been so successful that many Canadians have never seen the impact of these diseases, with some parents...
