Vaccine-induced ADE isn't usually a significant problem in the event of infection with the specific pathogen the vaccine was made for...I mean, it can have very bad consequences, but it isn't the worst.

The worst comes when a person 'inoculated' by a faulty vaccine is infected by a RELATED virus.

I.E., why did they take the first SARS vaccine off the market? It even seemed to work at first against SARS. Problem is, the next time they caught a damned cold they'd have a 20% mortality rate.

Same thing here. SARS, Sars-CoV-2 (cause of COVID), common cold? All coronaviruses.

So, if the SARS-CoV-2 vaccines does what the initial SARS vaccine did...people who are vaxxed will begin having a 1/5 chance of dying from what was previously called 'the sniffles' or 'a mild cold'.
