Meh.
Annual flu shots are similar in that they don't know which variants are going to be in play each year so they create a new "shot gun" type of vaccine hoping to have made a good educated guess. That is necessary every year to provide a modicum of resistance. I am comfortable with that and have taken the flu shot every year for the last 25+ or so years.
Certain vaccines are well known to require more than one dose, sometimes two, to be effective. If we have a new variant(s) and I can build anti-bodies to whatever variant(s) is/are out there at the time, I will gladly seek out the vaccination (unless I see something that concerns me).
YMMV
