After you are fully vaccinated for COVID-19, take these steps to protect yourself and others:
In general, you do not need to wear a mask in outdoor settings.
If you are in an area with high numbers of COVID-19 cases, consider wearing a mask in crowded outdoor settings and when you are in close contact with others who are not fully vaccinated.
If you have a condition or taking medications that weaken your immune system, you may not be fully protected even if you are fully vaccinated. You should continue to take all precautions recommended for unvaccinated people, including wearing a well-fitted mask, until advised otherwise by their healthcare provider.
If you are fully vaccinated, to maximize protection from the Delta variant and prevent possibly spreading it to others, wear a mask indoors in public if you are in an area of substantial or high transmission.
