In this post I link to and excerpt from Interim Public Health Recommendations for Fully Vaccinated People. Updated Aug. 19, 2021 from the CDC.
All that follows is from the above resource.
Summary of Recent Changes
Updates as of July 27,2021
- Updated information for fully vaccinated people given new evidence on the B.1.617.2 (Delta) variant currently circulating in the United States.
- Added a recommendation for fully vaccinated people to wear a mask in public indoor settings in areas of substantial or high transmission.
- Added information that fully vaccinated people might choose to wear a mask regardless of the level of transmission, particularly if they are immunocompromised or at increased risk for severe disease from COVID-19, or if they have someone in their household who is immunocompromised, at increased risk of severe disease or not fully vaccinated.
- Added a recommendation for fully vaccinated people who have come into close contact with someone with suspected or confirmed COVID-19 to be tested 3-5 days after exposure, and to wear a mask in public indoor settings for 14 days or until they receive a negative test result.
- CDC recommends universal indoor masking for all teachers, staff, students, and visitors to schools, regardless of vaccination status.On This Page

Currently authorized vaccines in the United States are highly effective at protecting vaccinated people against symptomatic and severe COVID-19. Fully vaccinated people are less likely to become infected and, if infected, to develop symptoms of COVID-19. They are at substantially reduced risk of severe illness and death from COVID-19 compared with unvaccinated people.
Infections in fully vaccinated people (breakthrough infections) happen in only a small proportion of people who are fully vaccinated, even with the Delta variant. Moreover, when these infections occur among vaccinated people, they tend to be mild. However, preliminary evidence suggests that fully vaccinated people who do become infected with the Delta variant can be infectious and can spread the virus to others.
Data suggest immune response to COVID-19 vaccination might be reduced in some immunocompromised people including, but not limited to, people receiving chemotherapy for cancer, people with hematologic cancers such as chronic lymphocytic leukemia, people receiving stem cells or organ transplants, people receiving hemodialysis, and people using certain medications that might blunt the immune response to vaccination (e.g., mycophenolate, rituximab, azathioprine, anti-CD20 monoclonal antibodies, Bruton tyrosine kinase inhibitors).
People with moderately to severely compromised immune systems should receive an additional dose of mRNA COVID-19 vaccine after the initial 2 doses.
People who are immunocompromised should be counseled about the potential for reduced immune responses to COVID-19 vaccines and the need to continue to follow current prevention measures (including wearing a mask, staying 6 feet apart from others they don’t live with, and avoiding crowds and poorly ventilated indoor spaces) to protect themselves against COVID-19 until advised otherwise by their healthcare provider. Close contacts of immunocompromised people should also be encouraged to be vaccinated against COVID-19.
This guidance provides recommendations for fully vaccinated people, including:
- How fully vaccinated people can safely resume many activities while protecting others.
- How fully vaccinated people should approach domestic and international travel.
- How fully vaccinated people should approach isolation, quarantine, and testing.
CDC will continue to evaluate and update public health recommendations for fully vaccinated people as more information, including on Delta and other new variants, becomes available. Further information on evidence and considerations related to these recommendations is available in the Science Brief.
Guiding Principles for Fully Vaccinated People
- Outdoor activities pose minimal risk to fully vaccinated people.
- Most indoor activities pose low risk to fully vaccinated people, especially in areas with low or moderate transmission.
- Infections happen in only a small proportion of people who are fully vaccinated, even with the Delta variant.
- Fully vaccinated people who become infected with the Delta variant can transmit it to others.
To reduce their risk of becoming infected with the Delta variant and potentially spreading it to others, CDC recommends that fully vaccinated people:
- Wear a mask in public indoor settings if they are in an area of substantial or high transmission.
- Fully vaccinated people might choose to mask regardless of the level of transmission, particularly if they or someone in their household is immunocompromised or at increased risk for severe disease, or if someone in their household is unvaccinated.
- Get tested if experiencing COVID-19 symptoms.
- Isolate if they have tested positive for COVID-19 in the prior 10 days or are experiencing COVID-19 symptoms.
- Get tested 3-5 days after exposure to someone with suspected or confirmed COVID-19 and wear a mask in public indoor settings for 14 days after exposure or until they receive a negative test result.
- Continue to follow any applicable federal, state, local, tribal, or territorial laws, rules, and regulations.
Recommendations for Isolation, Quarantine and Testing
The following recommendations apply to non-healthcare settings. Guidance for residents and staff of healthcare settings can be found in the Updated Healthcare Infection Prevention Control Recommendations in Response to COVID-19 Vaccination.
Fully vaccinated people with COVID-19 symptoms
Although the risk that fully vaccinated people could become infected with COVID-19 is low, any fully vaccinated person who experiences symptoms consistent with COVID-19 should isolate themselves from others, be clinically evaluated for COVID-19, and tested for SARS-CoV-2 if indicated. The symptomatic fully vaccinated person should inform their healthcare provider of their vaccination status at the time of presentation to care.
Fully vaccinated people with no COVID-like symptoms following an exposure to someone with suspected or confirmed COVID-19
Fully vaccinated people who have come into close contact with someone with COVID-19 should be tested 3-5 days following the date of their exposure and wear a mask in public indoor settings for 14 days or until they receive a negative test result. They should isolate if they test positive. Fully vaccinated people who live in a household with someone who is immunosuppressed, at increased risk of severe disease, or unvaccinated (including children <12 years of age) could also consider masking at home for 14 days following a known exposure or until they receive a negative test result. Most fully vaccinated people with no COVID-like symptoms do not need to quarantine or be restricted from work following an exposure to someone with suspected or confirmed COVID-19, if they follow the testing and masking recommendation above.
Fully vaccinated people should monitor for symptoms of COVID-19 for 14 days following an exposure.
Fully vaccinated people with no COVID-19-like symptoms and no known exposure to someone with suspected or confirmed COVID-19
It is recommended that fully vaccinated people with no COVID-19-like symptoms and no known exposure should be exempted from routine screening testing programs, if feasible.
