US CDC plans study into vaccines and autism, sources say

The U.S. Centers for Disease Control and Prevention is planning a large study into potential connections between vaccines and autism, two sources familiar with the matter told Reuters, despite extensive scientific research that has disproven or failed to find evidence of such links.

The CDC's move comes amid one of the largest measles outbreaks the U.S. has seen in the past decade, with more than 200 cases and two deaths in Texas and New Mexico. The outbreak has been fueled by declining vaccination rates in parts of the United States where parents have been falsely persuaded that such shots do more harm than good.

U.S. Health Secretary Robert F. Kennedy Jr, whose role includes authority over the CDC, has long sowed doubt over the safety of the combined vaccine for measles, mumps and rubella (MMR). In a cabinet meeting last week, Kennedy initially downplayed news that a school-aged child had died of measles in Texas, the first such death in a decade, calling such outbreaks ordinary and failing to mention the role of vaccination to prevent measles.

Last weekend Kennedy published an opinion piece on Fox News that promoted the role of vaccination, but also told parents vaccination was a personal choice and urged them to consult with their physician.

HHS and CDC cited what they described as skyrocketing autism rates in a joint statement on Friday.

"CDC will leave no stone unturned in its mission to figure out what exactly is happening," the statement said. "The American people expect high quality research and transparency and that is what CDC is delivering."
