A COVID-19 vaccine may be available to a portion of the U.S. in limited supplies by this winter.
A U.S. Army vaccine researcher said it's possible a coronavirus vaccine could be available by the end of the year.
"it's reasonable to expect that there will be some form of a vaccine that could be available at some level, to a certain population, by the end of the year.”

Researchers told Reuters the U.S. is planning to test the vaccine on more than 100,000 volunteers.
