So sorry to hear you were infected. Had not heard of the "gastro-intestinal" type, mainly the lung infection type, possibly requiring respirators. You are now fully recovered?
Regards the vaccine, I've heard reports that over 100 are in development. And 6 or 8 have been approved for clinical trial.
The vaccine may not be a silver bullet, but I will take the chance when it is available (if proven not to make things worse).
We have to wait and see what the science says, the trials should give us an idea of the efficacy.
