Another new study worth looking into-- Delta variant #covid19 outbreak in a London nursing home.

Many residents/staff were <14 days since receiving dose 2 of Astra Zeneca vaccine; secondary attack rate among partially vaxx residents was 81.3% (13/16)

eurosurveillance.org/content/10.280…

2/ Table 1 has a break down by demographics and vaccination status

Unique situation here as most residents/staff were getting dose 2 right when the index case was diagnosed with #covid19

3/ Reassuring- hospitalization uncommon; no deaths here. And this was among a care home population where we know #covid19 has caused immense suffering/death this past year.

Index case here was described as getting dose 1 in January, but unclear whether they ever got dose 2.

4/ Less surprising- nursing home residents (likely older + comorbidities) comprised twice as many cases as did the staff, despite there being equal numbers in both groups. #covid19

Somewhat surprising--> 3 people were >14 days post dose 2; all 3 reported as becoming cases.

5/ But- as mentioned in previous threads-- testing positive on rtPCR is very different than having clinically significant disease. From this study, it seems that there were no deaths and very few hospitalizations, which is reassuring.

And this is in a nursing home. #covid19
