herd stupidity 

Having preference for the epidemiological condition resulting in reduction of airborne communicable disease transmission requiring 60-70 percent of a given, closed community to have acquired natural immunity to the infection at the expense significant mortality when targeted immunization protocols can achieve the same objective without inherent suffering.

COVID-19 infection? Get you some! Put away yer mask, gimme a high-five and let's party with the germs!
Ummm. I think I'll wait for the vaccine rather than jump on your herd stupidity train.

Herd-stupidity 

A form of indirect protection from rational thinking that occurs when a large percentage of a population has become immune to using their brains, whether through group think or mainstream media influence , thereby providing a measure of isolation for individuals who are not so afflicted.

We seem to be protected from making any progress as society has achieved herd-stupidity
