herd immunity
This term describes a population-level phenomenon rather than an individual medical state. It carries a strong connotation of collective responsibility and public health strategy, often appearing in political and scientific discourse regarding vaccination campaigns.
As an uncountable noun, it refers to a state of being or a threshold of resistance. It does not have a plural form and cannot be counted as individual units; instead, it is measured by the percentage of the population that is immune.
Meanings
