While no one’s talking about it, I would imagine that a real vaccine is under development, one using dead virus like the flu shots. They’ll have to include the various strains just as the flu shot does. That will be another option for those who think the current shot is too risky.
This can only be done if the virus has been isolated, so far that has not been done. That is one reason why this "experimental" vaccine doesn't work, at all.
