On-Time Vaccine Receipt in the First Year Does Not Adversely Affect Neuropsychological Outcomes
This article, published in the journal Pediatrics, examines whether children who received recommended vaccines on time during the first year of life had different neuropsychological outcomes at 7 to 10 years of age as compared with children with delayed receipt or nonreceipt of these vaccines. The researchers used publicly available data, including age at vaccination, from a previous VaccineSafety Datalink study of thimerosal exposure and analyzed 42 neuropsychological outcomes. Results showed that timely vaccination during infancy has no adverse effect on neuropsychological outcomes 7 to 10 years later. These data may reassure parents who are concerned that children receive too many vaccines too soon.
