Usage of Anti-Vaxxer

As a result of the global COVID-19 pandemic, the use of the term anti-vaxxer has both increased and broadened. Anti-vaxxer came to the fore most prominently in the context of childhood immunization, where it is used to refer to someone who opposes the use of vaccines and who is also against policies, laws, etc. requiring vaccination for inclusion in a certain activity (such as attending school).

Ironically, most of the COVID anti-vaxxers have been vaccinated against most other diseases, from measles to TB to meningitis, which makes their resistance to COVID vaccines all the more baffling.

—Chris Freind

The term anti-vaxxer is sometimes applied to people who are not against the use of vaccines but who do oppose policies, laws, etc. that require vaccination. People with such views often object to being characterized as anti-vaxxers.

"Saying I'm against coercion or mandates is not the same as (telling people not to be vaccinated). I've had all of my vaccinations and took my daughter to the doctor the other day to get her vaccinations. I'm not an anti-vaxxer."

—George Christensen, quoted in Mackay (Australia) Daily Mercury Online

The revelations led to suggestions that [Jessica] Biel [actor] herself was an anti-vaxxer, which she denied on Thursday. "I am not against vaccinations—I support children getting vaccinations and I also support families having the right to make educated medical decisions for their children alongside their physicians," Biel wrote on Instagram. She added that her concern with the legislation "is solely regarding medical exemptions."
