A ridiculous mask study has been retracted: It found “Masks interfered with O2-uptake and CO2-release and compromised respiratory compensation” and concluded “mask wearing should not be mandated let alone enforced by law.” Objections were raised, and the journal investigated, concluding “the complaints were valid and that the article does not meet the standards of editorial and scientific soundness.”

Masks work. #WearAMask #COVID19

One technique of misinformation campaigns is to tell the big lie and then quietly retract it once it has done what you wanted. Your targets will remember the lie and not the retraction.
