Robert F Kennedy Jr

NY Times -  Health Secretary Robert F. Kennedy Jr. has said little publicly about vaccines in recent months, at the behest of a White House worried that his unpopular stance will hurt Republicans in November’s midterm elections. But he has not abandoned his quest for evidence that they are unsafe.

Working behind the scenes, Mr. Kennedy is spearheading an intense push, across health agencies under his purview, for government scientists and federal data contractors to examine his long-held theory that vaccines are helping to fuel an epidemic of chronic disease, according to multiple people familiar with the effort.

They said the wide-ranging inquiry is a top priority for Mr. Kennedy, who sees vaccines as a “potential culprit” in various neurological and autoimmune disorders, including asthma and allergies. It resurrects research into a number of ideas Mr. Kennedy has espoused, including whether vaccines are linked to autism and whether thimerosal, a preservative that has largely been removed from vaccines in the United States but remains in some flu shots, is dangerous.
