Query: An antivaccine pediatrician peddles bad information

If you're a parent looking for quality information on how best to protect your child from serious preventable diseases, Jay Gordon is a poor source.As can be judged not only by this video but by articles on his website and elsewhere, Gordon ignores the vaccine recommendations of the American Academy of Pediatrics and other leaders in the field of child and public health, in favor of his own claimed experience and antivaccine prejudices.Gordon acknowledges discouraging parents from taking advantage of vaccines and (as of August 2010) has a glowing tribute on his website to the disgraced researcher Andrew Wakefield, whose flawed research and scaremongering about the MMR vaccine led to a resurgence of measles in Great Britain.Listening to Gordon will put your child at risk.
