Autism and Vaccines

Autism and Vaccines Is there an association between the MMR and autism? Is there an association between thimerosal-containing vaccines and autism? What about Tylenol around the time of MMR vaccination? What does Dr. Erika think is happening?  What does Dr. Erika recommend? (With the understanding that this is just based on common sense, and not necessarily on science…) Research citations for Autism and Vaccines Geier DA, Kern JK, Geier MR.

Association Between Influenza Infection and Vaccination During Pregnancy and Risk of Autism Spectrum Disorder. JAMA Pediatr. 2017 Jan 2;171(1):e163609. “There was no association between maternal influenza infection anytime during pregnancy and increased ASD risk. There was a suggestion of increased ASD risk among children whose mothers received an influenza vaccination in their first trimester, but the association was not statistically significant after adjusting for multiple comparisons, indicating that the finding could be due to chance. These findings do not call for changes in vaccine policy or practice, but do suggest the need for additional studies on maternal influenza vaccination and autism.” Goin-Kochel RP, Mire SS, Dempsey AG, et al.
