I know it’s not Disney related, but I’m sharing because it’s been officially confirmed by Universal:
Updated Safety Guidelines
In accordance with CDC guidelines, face coverings are no longer required for fully vaccinated guests, indoors or outdoors. While we do not require proof of vaccination, we do expect those who are not fully vaccinated to wear face coverings while indoors. We encourage all guests to keep a safe distance between travel parties, and we remain focused on maintaining the highest cleanliness and sanitization standards.
