Vaccine Trickle Becomes Torrent as U.S. Eligibility Rules Widen Bloomberg 2 hrs ago (Bloomberg) -- It’s taking some effort and some patience.

Becky Jacobsen, 41, was ready to drive as long as an hour for a shot as soon as Connecticut made all adults eligible on Thursday. A friend stayed up late to snatch an appointment at a CVS Health Corp. drugstore just 6 miles from Jacobsen’s home in Windsor.
