Pro-vaccine activists who display religious, fanatical, or cult-like fervor despite evidence of vaccine related injury or death. Vacctivists will usually resort to logical fallacies in their arguments, such as; ad hominem and strawman attacks, guilt by association, and appeal to emotion (fear) to make their case. Vacctivism can be associated with social hypochondria and personal health insecurity which can lead to an obsession about how other people choose to live their lives, on a delayed schedule or vaccine-free.
