I think some people's definition of an "anti-vaxer" is getting too enlarged. If Paul Offit (member of VRBPAC, and the author of a book titled "Deadly Choices: How the Anti-Vaccine Movement Threatens Us All"), the Advisory Committee on Immunization Practices (ACIP, the advisory group to the CDC), the Vaccines and Related Biological Products Advisory Committee (VRBPAC, the advisory group for the FDA) are all anti-vaxers because they share similar views to the author, there might be a problem.
