The goal is not to immunize, but to prevent hospitalizations (at least their goal according to the article). If this infection is downgraded to a cold level that doesn't damage the lungs, would that be a problem? That said, I'm not sure other vaccines will be dropped. If any of the other candidates can give sterilizing immunity, that would be preferred. The "race" is just to avoid shutting down the whole world again, and many governments are afraid of an uptick of cases in the winter.
