Specifically, content that falsely alleges that approved vaccines are dangerous and cause chronic health effects, claims that vaccines do not reduce transmission or contraction of disease, or contains misinformation on the substances contained in vaccines will be removed. This would include content that falsely says that approved vaccines cause autism, cancer or infertility, or that substances in vaccines can track those who receive them. Our policies not only cover specific routine immunizations like for measles or Hepatitis B, but also apply to general statements about vaccines.
As with our COVID guidelines, we consulted with local and international health organizations and experts in developing these policies. For example, our new guidance on vaccine side effects maps to public vaccine resources provided by health authorities and backed by medical consensus. These policy changes will go into effect today, and as with any significant update, it will take time for our systems to fully ramp up enforcement.
There are important exceptions to our new guidelines. Given the importance of public discussion and debate to the scientific process, we will continue to allow content about vaccine policies, new vaccine trials, and historical vaccine successes or failures on YouTube. Personal testimonials relating to vaccines will also be allowed, so long as the video doesn't violate other Community Guidelines, or the channel doesn't show a pattern of promoting vaccine hesitancy.
