National Vaccine Information Center (NVIC). The NVIC is known for promoting false and misleading information about vaccines, in particular the discredited claim that vaccines cause autism. The ICA's annual conferences have featured anti-vaccination propaganda. In 2018 Guest Speaker Beau Pierce (Pierce co-produced a series entitled
Vaccines Revealed) hosted a session entitled Vaccines Revealed., and Jeff Hays, known for producing the anti-Vaccine propaganda
Vaccines Revealed, was invited to host a session the 2017 ICA Council on Chiropractic Pediatrics Annual Conference. In 2016 the widely discredited anti-vaccination propaganda film
