The Center for Health Policy Evaluation in Long-Term Care have published a report comparing the weekly rate of new COVID infections among staff and residents in nursing homes that had held a first vaccine clinic, compared to nursing homes in the same county that had not held a vaccine clinic yet.

They found that the rate of COVID-19 cases among staff and residents decreased faster in the 797 homes that had completed a first vaccine clinic with the Pfizer vaccine, than in the 1,709 facilities that had not held a clinic yet.

Three weeks after the 1st vaccine clinics:

• Vaccinated nursing homes experienced a 45% decline in new cases of infection among their residents, compared to a 21% decline in nonvaccinated nursing homes.
• Among staff, cases of infection declined by 33% in vaccinated nursing homes, compared to 18% in non-vaccinated care homes.
