The bottom line is that at some point there will be a risk level that will have to be carried and lived with. Variants that are occurring in the virus will vary from those that current vaccines will deal with whilst some will require vaccine modifications to deal with them. There will have to be monitoring of virus strains so that vaccines can be “tweaked”.
As time passes more data on long term vaccine effect will determine future needs for re-vaccination based on testing and checking on new strains of virus to see how vaccines cope with them.
My hope is that an organisation like WHO or similar are globally backed to watch for and investigate future outbreaks. I seem to remember Obama being keen for this but could be wrong.
I think we are in for a couple of years (maybe more) of readjustment to living with this virus. A global effort is needed, hence a logical move for a suitable overseeing organisation with as much depoliticising as possible.
