Hesitancy on the part of long-term-care-facility staffers to receive Covid-19 vaccinations is slowing the rollout of the shots to the nation's nursing homes and assisted-living centers, CVS Health Corp. said Wednesday.

Another factor driving lower-than-anticipated rollout numbers: Initial estimates by the facilities overstated the number of people living in them by about 20% to 30%, CVS said. During the pandemic, families have been reluctant to send relatives to nursing homes, which have been linked to more than 115,000 deaths.

"Based on feedback from our field teams, we've encountered more vaccine hesitancy among staff when compared with residents," a CVS spokesman said. Facilities are also staggering dosing to staff because of potential side effects, which has extended the process.

The pharmacy giant said it is still on track to reach federal goals to deliver first doses at about 8,000 skilled-nursing facilities by Jan. 25. Walgreens Boots Alliance Inc. said Wednesday that it also expects to complete the administration of the first doses in skilled-nursing facilities by Jan. 25.

CVS and Walgreens said they are also preparing to provide vaccinations to the general public by appointment at their drugstores once they become available for mass distribution later this year. Currently CVS and Walgreens are only authorized to administer vaccines at long-term-care facilities under a federal contract.

"Since receiving our first allotments of vaccines in late December, Walgreens has remained on track in vaccinating our most vulnerable populations," Walgreens President John Standley said.

The federal government fell far short of its promise to vaccinate 20 million people by the end of 2020. Of the more than 17 million doses of vaccines from Moderna Inc. and Pfizer Inc. with BioNTech SE that have been shipped, only 4.8 million have been administered, according to federal figures.

More than 429,000 doses have been administered at long-term medical-care centers. Facilities are getting shots at varying rates via CVS and Walgreens because states met the requirements to begin the distribution program at different times.

The American Health Care Association and National Center for Assisted Living said the rollout to long-term-care facilities is on track, while resistance among workers to receive the shots presents a challenge.

"As with any effort of this scale, there will be issues, and vaccine hesitancy is our primary focus at this moment," the organization said in a statement. "Staff seem to be mirroring the general public's reaction: excitement mixed with hesitation about the vaccines' development and safety."

CVS said long-term-care facilities based their population estimates on bed count, which is significantly higher than the number of residents living in them at any given time. CVS also said the shortfall is due in part to a lag in reporting data, which is shared publicly 48 to 72 hours after state registries and the Centers for Disease Control and Prevention receive the information.

Larry Merlo, CVS Health's chief executive, said the vaccination effort is challenging because it requires health-care providers to make in-room visits to each resident at the facilities that are part of the program.

The company said it is administering vaccines in skilled-nursing facilities in 49 states, after it added 36 states and Washington, D.C., to its rollout last week. By next week, states will have given CVS the go-ahead to begin vaccinations at nearly 31,000 assisted-living facilities, the company said.
