한글 기사는 좀 요상하게 났지만, 화이자 백신을 맞은 요양원에서 집단 발병이 일어났는데 백신을 맞은 사람보다 맞지 않은 사람이 3-4배 높은 감염율을 보였고, 백신 접종자의 80% 이상에서 증상이 없었다는 이야기 입니다.

백신을 접종받았다고 해서 감염되지 않는 것은 아니지만, 접종을 하는 것이 마땅하다는 결론을 내리고,
적어도 요양원 이상의 의료기관에서는 감염예방을 위한 조취를 계속 취해야 한다는 것을 보여주고 있습니다.

What is already known about this topic?

COVID-19 vaccines have demonstrated high efficacy in clinical trials. Limited data are available on effectiveness in skilled nursing facilities (SNFs) and against emerging variants.

What is added by this report?

In a COVID-19 outbreak at a Kentucky SNF involving a newly introduced variant to the region, unvaccinated residents and health care personnel (HCP) had 3.0 and 4.1 times the risk of infection as did vaccinated residents and HCP. Vaccine was 86.5% protective against symptomatic illness among residents and 87.1% protective among HCP.

What are the implications for public health practice?

Vaccination of SNF residents and HCP is essential to reduce the risk for symptomatic COVID-19, as is continued focus on infection prevention and control practices.
