The U.S. has plenty of Covid-19 vaccines but retail pharmacies are struggling to quickly administer them in some places.
Vaccine seekers in some states face waits of days or weeks for doses as local health officials hustle to improve access to meet surging demand . CVS Health Corp. /zigman2/quotes/209664499/composite CVS -0.81% , Walgreens Boots Alliance Inc. /zigman2/quotes/203410933/composite WBA -1.28% and Walmart Inc. /zigman2/quotes/207374728/composite WMT -0.73% , which are facing staffing shortages, now say they may not be able to accommodate people without appointments.
Millions of Americans are newly eligible for booster shots, and federal health officials in November recommended the vaccine for use in children as young as 5 years old . Concerns about the risks posed by the new omicron variant also are driving more people to get vaccinated , health officials say.
The U.S. was averaging about 1.5 million doses administered a day for a seven-day period as of Nov. 17, a nearly 12% increase from the previous week, according to the Centers for Disease Control and Prevention.
