WASHINGTON, Dec. 22 (Xinhua) -- Even though two types of COVID vaccines have been granted emergency use in the United States and one of them has started to be injected to health care workers, a flawed distribution formula may result in those most vulnerable to the coronavirus unable to get vaccinated in time.
The United States has a hierarchical system for vaccination where health care workers are the first in line to be inoculated, but the allocation of vaccines across states is based on the number of adults in each state, meaning health care workers in certain states may end up getting their doses later than those deemed lower priority in other states.
