Guest guest Posted February 22, 2010 Report Share Posted February 22, 2010 Who would of thought?! The CDC on its page for Autism Facts has an interesting bullet under causes. That bullet is about vaccines. Here is the CDCs exact words: " There is some evidence that the critical period for developing ASDs occurs before birth. However, concerns about vaccines and infections have led researchers to consider risk factors before and after birth. " Here is the web link for the page: http://www.cdc.gov/ncbddd/autism/facts.html What do you think it means? Quote Link to comment Share on other sites More sharing options...
