I think it's especially true because the most important aspect of vaccination is not really protection of the individual, even if it does accomplish that. It's getting as many people as possible vaccinated so that society as a whole has a good handle on the disease. If the 90% effective one is supply constrained and has this complicated 2 dose thing, and the 60-some % is simple and available, you're still doing your part to make a serious dent in the spread of the disease overall. And if the death rate of covid is some low number x, making it 0.3x is a pretty good deal.
