How about acquired artificial active immunity, like a vaccine?

How long will that immunity last?

Will we have to get the COVID vaccine every year, like the influenza vaccine?

Or every ten years like the Tdap (Tetanus, Diphtheria, Pertussis) vaccine?

Or will it be a one and done like the smallpox vaccine that I got when I was a kid (young'uns can look it up on the Google)?
