So if you want to jump late in the game on getting jabbed for Corona, you would need the first two jabs, then all boosters up to the most recent variant booster. Think computer software, you have to get/buy the base software, then get all the upgrades. At what point can we jump right to the current booster/variant, which includes all previous variants.

We are witnessing the real time model for vaccine sales for Covid (not vaccines) being peddled as software. If you are not awake yet, you better get there fast.
