Greetings!
There is a new CDC Guidance updated on Monday August 23, 2021, that provides a good explanation of breakthrough infections of Covid-19 variants in people who are fully vaccinated. This guidance also reiterates the CDC recent recommendations
on mitigation methods for fully vaccinated people, and discusses immunocompromised people.
It may be of use to libraries in determining COVID-19 policies and procedures.
Take Care!
Clare
