There is no reasonable hypothesis for how humeral vaccines could induce antibodies in the mucosae, therefore stop viral replication there, and therefore reduce shedding and hence infection of others. Nasal vaccines perhaps, which are an exciting development and may be what actually ends the outbreak, but not the current lot.

To be able to claim the current vaccines reduce spread you either have to propose how humeral vaccines delivered to the blood could induce T cells in the mucous membranes of the nose and throat, or suggest another mechanism by which the virus can spread.

So you're saying case rates are only dropping because of masks?

I didn't mention masks nor the effect or lack of effect of the current vaccines on case rates, I only added a supporting statement to the previous comment that they are doing very little to stop spread.
