Yes they don't know how it will be but they sure are pushing the vaccine even though there are effective treatments for it already. We'll have to see how this goes but unfortunately I think big money is influencing what's going on.If the COVID-19 virus has not mutated in some material way, a vaccine would be highly effective. What I don't think anyone really knows yet is whether it is mutating in ways that could make a vaccine more like seasonal flu vaccines or more like the polio vaccine. It's an incredibly evil and clever bug (considering that it isn't even really "alive" in any common sense).
