A study published earlier this month concluded African-American boys are more at risk for autism if they're given the measles, mumps and rubella vaccine before the age of 2. The study author says researchers at the Centers for Disease Control and Prevention knew about the link in 2004 -- and covered it up.
CDC researchers are standing by their original findings: that there is no link between autism and vaccination schedules.
The new study was funded by the Focus Autism Foundation, which says it is dedicated to exposing the causes of autism, "focusing on the role of vaccinations."
The study has since been removed from the public domain pending further investigation, according to Translational Neurodegeneration.
In an online statement, the scientific journal said the paper had been removed "because of serious concerns about the validity of its conclusions."
CNN first became aware of the study when an iReport was posted about its publication and the controversy surrounding it. iReport is CNN's user-generated news community.
