Q: Do individuals need to wear a mask and avoid close contact with others if they have received two doses of an mRNA vaccine or a single dose of the (J&J) vaccine?
A: According to the CDC, 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 regardless of vaccination status. Please note that these recommendations from the CDC don’t apply to healthcare settings including doctor’s offices and hospitals; transportation hubs like airports and train stations; correctional facilities and homeless shelters.
