The pattern has largely become Fauci hints at upcoming change, but then the change is very incremental and disappoints many people.
His first hint at a change in guidelines for those that were vaccinated -- High expectations that vaccinated people could lift most restrictions -- Became, "it's now safe to have small gatherings with other fully vaccinated people, or a small unvaccinated low risk pod"
First hint about change to outdoor masking guidelines -- became continue to wear masks outdoors in crowded areas. But can dine outdoors without masks with vaccinated people, don't need masks when alone outdoors, small private outdoor gatherings, etc.
They literally just extended the requirement for masks on Federal regulated transportation (airlines) until September. There may be some incremental indoor masking guidelines changed soon, but nothing that gets rid of masks in indoor public gathering places.
