It may take until next year for Michigan health officials to reach their goal of inoculating three-quarters of residents over the age of 15 against COVID-19, unless more doses of vaccine are made available.
Michigan is receiving just over 180-thousand doses of the two vaccines currently available each week.
But Michigan Governor Gretchen Whitmer says the state could inoculate 50-thousand people a day, if it had enough vaccine.
Whitmer had recently requested permission from the Trump Administration for Michigan to buy an additional 100-thousand doses of the Pfizer COVID-19 vaccine.
President Biden set a goal of having 100-million vaccinations during the first hundred days of his new administration.
The federal government is also preparing to weigh whether to recommend two additional vaccines against COVID-19.
