Yeah, they are probably referring to the nasal vaccines. They are working on them, and showing some progress, but it's been traditionally hard to pull off and I haven't heard of a timeline for their availability. If we get vaccines that provide mucosal immunity it will help a lot, from what I understand it would head off the virus before it enters the bloodstream and drastically lower transmission rates.
