In accordance with the updated guidance released by the Centers for Disease Control and Prevention (CDC) on “Interim Public Health Recommendations for Fully Vaccinated People,” issued July 27, 2021, the above reference is hereby rescinded.
Beginning July 28, 2021:
CDC guidance and definitions of low, moderate, substantial, and high spread can be found at: https://www.cdc.gov/mmwr/volumes/70/wr/pdfs/mm7030e2-H.pdf. Data on levels of community transmission can be found at the CDC COVID Data Tracker website found at: https://covid.cdc.gov/covid-data-tracker/.

The Department will review and revise all applicable Force Health Protection guidance to address the new CDC guidelines. Further guidance will be provided as appropriate by the Under Secretary of Defense for Personnel and Readiness (USD(P&R)).
