First, the two of the four currently used in the US that are mRNA "vaccines" account for over 90% of the total. Second, mRNA vaccines carry NO viruses. If you think they do, you do not understand the technology. They are lipid nanoparticles (think like a bubble that you blow with soap) within which they carry the spike protein mRNA (no virus whatsoever). No viruses are used in their creation, or testing. No viruses at all are used in any part of the production of the mRNA immunotherapies.
The adenovirus vaccines (still really an immunotherapy, since its not an actual part of the virus it is designed to provide immunity against) do have real viruses. They use an adenovirus carrier with its replicative DNA removed, and the spike protein DNA put in. This one can maybe shed, but in such small amounts as to be ridiculous because the max viral load is on injection. It never produces more of itself so the viral load is so small, any shedding would be minimal (if there is any at all).
So no, for all intents and purposes, with any meaningful measure, these vaccines can not shed, because they are not REAL virus vaccines (no possible replication -> no increased viral load -> no "shedding" (which really just means normal viral transmission from real vaccines that use real viruses)).
