The group that represents most Pediatricians in the USA (60 thousand members) is the American Academy of Pediatrics and they support giving the vaccine.
the group you quote is listed having an address in Gainesville Florida, was started in 2002, does not require you to be a pediatrician to join, has no information on how many belong except to say they have members in "47 states".
Thank you for pointing this out. Looking a little more...
Browsing their site leads to a link for qualifications for membership:
“Fellow
An applicant for Fellow in the American College of Pediatricians shall satisfy the following criteria:
1. Certification in pediatrics by the American Board of Pediatrics or the American Osteopathic Board of Pediatrics, or any other certification as determined by the Board of Directors.
2. Demonstration of evidence of high ethical and professional standing.
...
Specialty
An applicant for Specialty Fellow in the American College of Pediatricians shall satisfy the following criteria:
1. Licensed physician, other than a pediatrician, credentialed by an American Board in a pediatric discipline, or documented training devoting 50% or more time to pediatric patients
2. Demonstration of evidence of high ethical and professional standing...”
So it would seem that pediatrics is a requirement, even if being a “pediatrician” per se is not.
I am not sure if this is different from the AAP, whose site says:
“The AAP is an organization of 60,000 primary care pediatricians, pediatric medical subspecialists and pediatric surgical specialists.
Immunizations are one of several strategic priorities for the AAP. “
The difference seems to lie in interpretation of criterion 2. I suspect that many of our Catholic doctors may have interest in the “college”
I also suspect the the Academy is less likely to question any form of vaccination, while noting that “support[ing] giving the vaccination” is different from supporting mandating the vaccination, which is the subject of the instant controversy.
