ADE is more a problem for the vaccine approaches. It is one reason we may never have a vaccine for this disease.
Hard to rule out worst case scenarios, we just have to work with what we have and make hard choices.

This is at least partly why there are no SARS/MERS vaccines. There's a paper I'll try to dig up where 4-8 (can't remember) modified vaccine candidates were tested in multiple animal species, and in each case except one, immunity was conferred but exposure to the virus lead to a dangerous autoimmune response which destroyed lung tissue.
That's why I'm waiting for confirmation of immunity. So far I've only seen increasing numbers of reports of reinfection but that may just be faulty testing.
