| YouTube is taking down several video channels associated with high-profile anti-vaccine activists, including Joseph Mercola and Robert F. Kennedy Jr., as part of a new set of policies aimed at cutting down on anti-vaccine content on the Google-owned site. YouTube will ban any videos that claim that commonly used vaccines approved by health authorities are ineffective or dangerous. The company previously blocked videos that made those claims about coronavirus vaccines but not ones for other vaccines, such as those for measles or chickenpox. |
