COVID-19 Outbreak Associated with a SARS-CoV-2 R.1 Lineage...
"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.
...
Three residents died, two of whom were unvaccinated (VE = 94.4%; 95% CI = 44.6%–99.4%).
Four possible reinfections were identified (one resident and three HCP); of these, one HCP was vaccinated. All four persons experienced symptomatic illness. One resident was infected 300 days earlier and had nine consecutive negative RT-PCR tests before reinfection, including two within 30 days of the outbreak. This resident was hospitalized and died."

Being vaccinated won't be not enough, we need herd immunity.
