Immunity isn't a binary thing and it's not forever. The idea that you're either protected or not is completely incorrect. Protection against severe disease still wanes and it is less effective when you encounter a variant that's different from the one that you were immunized against or infected by. Anyone at risk of severe disease (50+ year olds and those with comorbidities) should jump at the chance to get an updated vaccine assuming it's shown to be effective. The immunity and protection will likely be much better and more long lasting.

Completely agree it's not binary or forever. I'm just talking about the timing of the Omicron vaccine and protection against Omicron. It appears the current vaccines don't fully immunize from Omicron, but it provides some protection from worse symptoms and reduces likelihood of hospitalization. IMO, it's not worth getting an additional Omicron vaccine in March (I think spread of Omicron will be very limited in Canada by March anyways) if you already have 2 doses and a booster. This may prove useful if they can very quickly churn out new vaccines for potential new variants that are more resistant to previous vaccines or more deadly.
