    Oh I am sure at least some will work but it will be a long time before anyone can be really sure, and although other Corona virus strains are common and been around for a long time this SARS-Covid-19 version is new to us and seems a particularly tough and flexible one.

    Like the vaccine for Influenza (also a Corona-virus disease) we may also need annual doses to keep up with the virus mutating slightly for its own survival.
