anti-vaccine movement

Anti-vaccine activism, which collectively constitutes the "anti-vax" or "anti-vaxx" movement, is a set of organized activities expressing opposition to vaccination. These collaborating networks often seek to increase vaccine hesitancy by disseminating vaccine misinformation and disinformation. As a social movement, it employs tools ranging from traditional news media to various forms of online communication. Activists have primarily—though not exclusively—focused on opposing childhood vaccination, and have sought to expand their influence from niche subgroups into national political debates.
