No scientific link between childhood vaccines and autism

A new article recently published in the Journal for Specialists in Pediatric Nursing explored vaccination history, vaccine safety monitoring systems in the U.S., and the two most publicized theoretical vaccine-related exposures associated with autism – the vaccine preservative thimerosal and the measles, mumps, and rubella (MMR) vaccine. A review of published research shows that there is not convincing scientific evidence supporting a relationship between vaccines and autism. The article is part of a special issue, which includes five articles focusing on the topic of autism.

What I find puzzling is why people who are so fixated on finding a link do not seem to be concerned with the possible role of pollution in the environment.
