The problem we have with the vaccination is that we don't know how long the immunity is going to last. There are two issues, first the immunity could stop after 1 or 2 years and we would need to get a new vaccine. The second issue would be that there will be mutations on the future that are immune to the vaccine. It is hard to give probabilities to these events.
I have read it many times before that the immunity the vax provides only lasts 6 months at best. Not a year or two. They want everybody to get vaccinated every 6 months forever. This is not like the flu-shots which only the elderly people get after a certain age. They want this for everybody, forever.
Obviously, it is not going to happen.
