Can we stop precautions once an individual is vaccinated and has been proven to have immunity through antibody testing?
For healthcare settings precautions should still be used even if someone has been fully vaccinated and proven to have immunity from the vaccine. Employees and patients should still wear masks, practice social distancing, and frequently wash their hands until more is learned about the longevity and benefit of immunity from vaccination.
According to the CDC, the following recommendations apply to non-healthcare settings.
Fully vaccinated people can:
- Visit with other fully vaccinated people indoors without wearing masks or physical distancing,
- Visit with unvaccinated people from a single household who are at low risk for severe COVID-19 disease indoors without wearing masks or physical distancing,
- Refrain from quarantine and testing following a known exposure if asymptomatic.
For now, fully vaccinated people should continue to:
- Take precautions in public like wearing a well-fitted mask and physical distancing,
- Wear masks, practice physical distancing, and adhere to other prevention measures when visiting with unvaccinated people who are at increased risk for severe COVID-19 disease or who have an unvaccinated household member who is at increased risk for severe COVID-19 disease,
- Wear masks, maintain physical distance, and practice other prevention measures when visiting with unvaccinated people from multiple households,
- Avoid medium- and large-sized in-person gatherings,
- Get tested if experiencing COVID-19 symptoms,
- Follow guidance issued by individual employers,
- Follow CDC and health department travel requirements and recommendations.
