CDC: Breakthrough cases in Kentucky skilled nursing facility outbreak in March reached 25%

COVID-19 Outbreak Associated with a SARS-CoV-2 R.1 Lineage Variant in a Skilled Nursing Facility After Vaccination Program — Kentucky, March 2021:

Among 83 residents and 116 HCP, 75 (90.4%) and 61 (52.6%), respectively, received 2 vaccine doses. Twenty-six residents and 20 HCP received positive test results for SARS-CoV-2, the virus that causes COVID-19, including 18 residents and four HCP who had received their second vaccine dose >14 days before the outbreak began. An R.1 lineage variant was detected with whole genome sequencing (WGS). ... 25.4% of vaccinated residents and 7.1% of vaccinated HCP were infected.

Looks like Pfizer vaccines are somewhat less effective in older people, but there is no age data given in this report. Critics of the Pfizer trial say not enough old people were part of it. This would seem to bear that out.
 
Why are 90% of the residents vaccinated but only 52% of the workers who care for them?
 
Seems like an ongoing phenomenon for people "in the industry" to be vaccine hesitant.
