Starting in two weeks, states with the speediest vaccine rollouts will be prioritized.
The prioritization will be for additional doses, US officials announced Tuesday.
The new system is meant to incentivize states to promptly record vaccinations.
It will also prevent doses from sitting in freezers, says Business Insider.
But it could also punish states that lack the funding or resources to accelerate vaccine administration.
The strategy is set to take effect after President-elect Joe Biden takes office.
