IIRC the CDC says there is evidence that vaccinated individuals can spread the delta variant. So it's important for everyone to continue to wear masks, even those vaccinated. It helps keep those who can't get vaccinated safe, and it helps reduce load on the hospitals so people can get timely treatment for other concerns. Additionally, breakthrough cases are a breeding ground for further evolution of the virus.
