USA: At least 125,000 vaccine breakthrough infections, 1,400 dead

At least 125,000 fully vaccinated Americans have tested positive for Covid and 1,400 of those have died, according to data collected by NBC News.  The total number of breakthrough cases is likely higher than 125,683, since nine states, including Pennsylvania and Missouri, did not provide any information, while 11, like Florida, did not provide death and hospitalization totals. Four states gave death and hospitalization numbers, but not the full tally of cases.

USA: large covid-19 outbreak in Kentucky with R.1 #coronavirus lineage variant after vaccine breakthrough with Pfizer

The Kentucky Department for Public Health and a local health department investigated a COVID-19 outbreak in a skilled nursing facility that occurred after all residents and health care personnel had been offered vaccination. Among 83 residents and 116 health care personnel, 75 residents and 61 staff, respectively, received 2 vaccine doses. Twenty-six residents and 20 health care personnel received positive test results for SARS-CoV-2, the virus that causes COVID-19, including 18 residents and four health care personnel who had received their second vaccine dose >14 days before the outbreak began.

An R.1 lineage variant was detected with whole genome sequencing. Although the R.1 variant has multiple spike protein mutations, vaccinated residents and HCP were 87% less likely to have symptomatic COVID-19 compared with those who were unvaccinated. Vaccination of skilled nursing facility populations, including health care personnel, is critical to reduce the risk for SARS-CoV-2 introduction, transmission, and severe outcomes in skilled nursing facilities.
