Interim Public Health Recommendations for Fully Vaccinated People
Summary of Recent Changes
Updates as of May 28, 2021
- Updated Choosing Safer Activities infographic with new considerations for the example activity for outdoor gatherings with fully vaccinated and unvaccinated people.
The following recommendations apply to non-healthcare settings. For related information for healthcare settings, visit Updated Healthcare Infection Prevention and Control Recommendations in Response to COVID-19 Vaccination.
Fully vaccinated people can:
- Resume activities without wearing masks or physically distancing, except where required by federal, state, local, tribal, or territorial laws, rules and regulations, including local business and workplace guidance
- Resume domestic travel and refrain from testing before or after travel or self-quarantine after travel
- Refrain from testing before leaving the United States for international travel (unless required by the destination) and refrain from self-quarantine after arriving back in the United States
- Refrain from testing following a known exposure, if asymptomatic, with some exceptions for specific settings
- Refrain from quarantine following a known exposure if asymptomatic
- Refrain from routine screening testing if feasible
For now, fully vaccinated people should continue to:
- Get tested if experiencing COVID-19 symptoms
- Follow CDC and health department travel requirements and recommendations
Currently authorized vaccines in the United States are highly effective at protecting vaccinated people against symptomatic and severe COVID-19. Additionally, a growing body of evidence suggests that fully vaccinated people are less likely to have asymptomatic infection or transmit SARS-CoV-2 to others. How long vaccine protection lasts and how much vaccines protect against emerging SARS-CoV-2 variants are still under investigation.
For the purposes of this guidance, people are considered fully vaccinated for COVID-19 ≥2 weeks after they have received the second dose in a 2-dose series (Pfizer-BioNTech or Moderna), or ≥2 weeks after they have received a single-dose vaccine (Johnson & Johnson [J&J]/Janssen)±; there is currently no post-vaccination time limit on fully vaccinated status. Unvaccinated people refers to individuals of all ages, including children, that have not completed a vaccination series or received a single-dose vaccine.
At this time, there are limited data on vaccine protection in people who are immunocompromised. People with immunocompromising conditions, including those taking immunosuppressive medications (for instance drugs, such as mycophenolate and rituximab, to suppress rejection of transplanted organs or to treat rheumatologic conditions), should discuss the need for personal protective measures with their healthcare provider after vaccination.
This guidance provides recommendations for fully vaccinated people, including:
- How fully vaccinated people can safely resume activities
- 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 new variants, becomes available. Further information on evidence and considerations related to these recommendations is available in the Science Brief.
- Indoor and outdoor activities pose minimal risk to fully vaccinated people.
- Fully vaccinated people have a reduced risk of transmitting SARS-CoV-2 to unvaccinated people.
- Fully vaccinated people should still get tested if experiencing COVID-19 symptoms.
- Fully vaccinated people should not visit private or public settings if they have tested positive for COVID-19 in the prior 10 days or are experiencing COVID-19 symptoms.
- Fully vaccinated people should continue to follow any applicable federal, state, local, tribal, or territorial laws, rules, and regulations.
Risk of SARS-CoV-2 infection is minimal for fully vaccinated people. The risk of SARS-CoV-2 transmission from fully vaccinated people to unvaccinated people is also reduced. Therefore, fully vaccinated people can resume activities without wearing a mask or physically distancing, except where required by federal, state, local, tribal, or territorial laws, rules, and regulations, including local business and workplace guidance. Fully vaccinated people should also continue to wear a well-fitted mask in correctional facilities and homeless shelters. Prevention measures are still recommended for unvaccinated people.
Fully vaccinated travelers are less likely to get and spread SARS-CoV-2 and can now travel at low risk to themselves within the United States. International travelers need to pay close attention to the situation at their international destinations before traveling due to the spread of new variants and because the burden of COVID-19 varies globally.
CDC prevention measures continue to apply to all travelers, including those who are vaccinated. All travelers are required to wear a mask on all planes, buses, trains, and other forms of public transportation traveling into, within, or out of the United States and in U.S. transportation hubs such as airports and stations.
Domestic travel (within the United States or to a U.S. territory)
- Fully vaccinated travelers do not need to get a SARS-CoV-2 viral test before or after domestic travel, unless testing is required by local, state, or territorial health authorities.
- Fully vaccinated travelers do not need to self-quarantine following domestic travel.
- For more information, see Domestic Travel During COVID-19.
- Fully vaccinated travelers do not need to get tested before leaving the United States unless required by their destination.
- Fully vaccinated air travelers coming to the United States from abroad, including U.S. citizens, are still required to have a negative SARS-CoV-2 viral test result or documentation of recovery from COVID-19 before they board a flight to the United States.
- International travelers arriving in the United States are still recommended to get a SARS-CoV-2 viral test 3-5 days after travel regardless of vaccination status.
- Fully vaccinated travelers do not need to self-quarantine in the United States following international travel.
- For more information, see International Travel During COVID-19.
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
Most fully vaccinated people with no COVID-like symptoms do not need to quarantine, be restricted from work, or be tested following an exposure to someone with suspected or confirmed COVID-19, as their risk of infection is low.
However, they should still monitor for symptoms of COVID-19 for 14 days following an exposure.
Exceptions where testing (but not quarantine) is still recommended following an exposure to someone with suspected or confirmed COVID-19 include:
- Fully vaccinated residents and employees of correctional and detention facilities and homeless shelters.
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.
†This guidance applies to COVID-19 vaccines currently authorized for emergency use by the U.S. Food and Drug Administration: Pfizer-BioNTech, Moderna, and Johnson & Johnson (J&J)/Janssen COVID-19 vaccines. This guidance can also be applied to COVID-19 vaccines that have been authorized for emergency use by the World Health Organization (e.g. AstraZeneca/Oxford).
- Guiding principles for fully vaccinated people are now provided.
- Underscores that immunocompromised people need to consult their healthcare provider about these recommendations, even if fully vaccinated.
- Fully vaccinated people no longer need to wear a mask outdoors, except in certain crowded settings and venues.
- Clarification that fully vaccinated workers no longer need to be restricted from work following an exposure as long as they are asymptomatic.
- Fully vaccinated residents of non-healthcare congregate settings no longer need to quarantine following a known exposure.
- Fully vaccinated asymptomatic people without an exposure may be exempted from routine screening testing, if feasible.
