Science denialists and quacks love abusing Koch’s postulates to deny that various microorganisms are the true cause of disease; so it was inevitable that they’d do it for COVID-19.
Yesterday, antivaxxers were saying that the flu vaccine caused the Wuhan 2019-nCoV outbreak because of viral interference. Now the outbreak is due to a failed SARS coronavirus vaccine. Can they get their conspiracy theories straight?
Antivaccine activists are blaming the coronavirus outbreak in China on—what else?—the flu vaccine, because of course they are. All they have to do is to deceptively invoke “virus interference.” So science-y!
