Refusenik

Refusenik (Russian: отказник, otkaznik, from "отказ", "refusal") was an unofficial term for individuals, typically but not exclusively Soviet Jews, who were denied permission to emigrate abroad by the authorities of the former Soviet Union and other countries of the Eastern bloc.1 The term refusenik derived from the "refusal," handed down to a prospective emigrant from the Soviet authorities.

Over time, "refusenik" has entered colloquial English usage for any type of protester.

A science-denying anti-vaxxer who hasn't had a booster jab injected into them in the last 3 months. Usually found supporting Trump and wearing a tinfoil hat to protect themselves from something imaginary.

Person 1: "Hey brother, the wedding is next week. Have you had your 2027 Q3 booster yet?"
Booster Refusenik: " My Q2 booster just expired last week."
Person 1: "Well we can't invite you then sorry. We can't allow science-deniers like you to put the health of our boosted guests at risk."
