Details: The federal government is making three big changes, according to a senior administration official:

Recommending that states open the vaccination process to everyone older than 65 and to adults of all ages who have a pre-existing condition that puts them at greater risk for serious infection.

Expanding the venues where people can get vaccinated to include community health centers and more pharmacies.

Getting all the available doses out the door now. Both of the authorized vaccines require two shots; the government will no longer hold back doses for the second shot, but will instead try to get today’s doses into people’s arms now, trusting that supplies will increase rapidly enough to provide second shots.
