Abstract
Antibody decline occurred from 2 weeks to 6 months post-BNT162b2 mRNA vaccination in nursing home (NH) residents and healthcare workers. Antispike, receptor-binding domain, and neutralization levels dropped >81% irrespective of prior infection. Notably, 69% of infection-naive NH residents had neutralizing antibodies at or below the assay’s limit of detection.

항체 감소는 요양원(NH) 거주자와 의료 종사자에서 BNT162b2 mRNA 백신 접종 후 2주에서 6개월 사이에 발생했습니다. Antispike, 수용체 결합 도메인 및 중화 수준은 이전 감염과 관계없이 >81% 떨어졌습니다. 특히, 감염 경험이 없는 NH 거주자의 69%가 분석의 검출 한계 이하에서 중화 항체를 가졌다.
