Abstract
This study examines the personal beliefs held by parents of autistic children in Puerto Rico regarding the cause of their child’s autism and how these beliefs may influence parental vaccination decision-making. This study seeks to contribute towards diversifying the autism literature by focusing on an autism community living in a relatively lower income, resource-deficit context. These findings expand our understandings of how parents of autistic children may perceive vaccines and how these perceptions are informed by various sources of knowledge. This ethnographic research study was conducted between May 2017 and August 2019. Methods included 350+ hours of participant-observation and semi-structured interviewing of 35 Puerto Rican parents of autistic children. 32 of these 35 parents interviewed believed autism to be the result of genetic risks that are ‘triggered’ by an unknown environmental factor. Suggested ‘triggers’ included various environmental contaminants and vaccinations. The subject of vaccination came up in every interview; 18 interviewed parents did not believe vaccines ‘triggered’ autism, 3 parents attributed their child’s autism entirely to vaccines, while 14 considered vaccines to be one of several possible ‘triggers’. It is important to note that no parents interviewed perceived vaccinations to be inherently or universally harmful. Rather, they perceived vaccinations to be one of many possible ‘triggers’ for a child predisposed to develop autism. In some cases, this perception prompted parents to oppose mandatory vaccination policies on the island. Parents shared nuanced, complex understandings of autism causation that may carry implications for COVID-19 vaccine uptake within the Puerto Rican autistic community.
