Purpose: While a large body of evidence has shown that the administration of the measles-mumps-rubella (MMR) vaccine is not associated with an increased risk of autism spectrum disorder (ASD), a hesitant attitude towards childhood vaccination is still present among the public. In this study, we aim to investigate the mothers' perceptions of the cause of their child's ASD in order to increase our understanding of vaccine hesitancy.Methods: This study draws on the analysis of 18 semi-structured interviews of mothers of children with ASD on the causes of autism.Results: The interview material was content-analysed. The main themes were 1) childhood vaccines; 2) genetics; 3) specific conditions of the mother or the newborn at the moment of delivery; 4) environmental factors such as the mother's lifestyle or her diet. The link between vaccines and autism was prevalent. About one third of the mothers reported that their child's ASD was a consequence of a combination of two or more factors, i.e., childhood vaccines and specific conditions of the newborn or the mother at the moment of delivery.Conclusion: This study provides preliminary insights into recurring sets of beliefs concerning the causes of ASD among the mothers of affected children.

Incidence of measles is increasing in the US, largely due to transmission among growing unvaccinated communities. To elucidate predictors of parental decision to obtain measles, mumps, and rubella (MMR) vaccine for unvaccinated children during a measles outbreak, we surveyed families among a vaccine-hesitant Somali community in Minnesota. The survey assessed attitudes and beliefs about MMR vaccine, motivators for vaccinating, and intention to vaccinate future children on time. Among 300 families surveyed, 95% vaccinated their child with MMR due to fear of measles. The predominating parental concern about MMR vaccine (71%) was a fallacious presumed connection between vaccination and autism. Only 41% of parents intended to vaccinate future children on time with MMR; parents who received recommendations for MMR vaccination from multiple sources were more likely than other parents to intend to do so. These findings support the importance of diverse outreach efforts to increase vaccine coverage among undervaccinated communities.

One of the ten greatest public health achievements is childhood vaccination because of its impact controlling and eliminating vaccine-preventable diseases (VPDs). Evidence-based immunization policies and practices are responsible for this success and are supported by epidemiology that has generated scientific evidence for informing policy and practice. The purpose of this report is to highlight the role of epidemiology in the development of immunization policy and successful intervention in public health practice that has resulted in a measurable public health impact: the control and elimination of VPDs in the United States. Examples in which epidemiology informed immunization policy were collected from a literature review and consultation with experts who have been working in this field for the past 30 years. Epidemiologic examples (e.g., thimerosal-containing vaccines and the alleged association between the measles, mumps, and rubella (MMR) vaccine and autism) are presented to describe challenges that epidemiologists have addressed. Finally, we describe ongoing challenges to the nation's ability to sustain high vaccination coverage, particularly with concerns about vaccine safety and effectiveness, increasing use of religious and philosophical belief exemptions to vaccination, and vaccine hesitancy. Learning from past and current experiences may help epidemiologists anticipate and address current and future challenges to respond to emerging infectious diseases, such as COVID-19, with new vaccines and enhance public health impact of immunization programs for years to come.
