WOONSOCKET, R.I.  (CBS) — CVS Pharmacy locations all over the country, including 389 in Massachusetts, are now accepting walk-ins for COVID vaccines, “with no appointment necessary.” The announcement comes as President Joe Biden directed pharmacies participating in the federal vaccine program to make the shots more easily available.

“I know some people find making an appointment in advance inconvenient,” Biden said Tuesday. “So, starting this week, we are also going to direct all federal pharmacy partners to begin to provide walk-in hours.”
