This is not true, at all. The current crop of vaccines are roughly 95% non-sterilizing. It IS true that they reduce net transmission, but the literature is clear that the reason is almost exclusively due to how they shorten the duration of carrying. The nasal viral load is virtually identical. The primary factor is how long you're carrying that load for (approximately 11 days vs 8 days from what I can tell from pubmed et al). Does vaccination help the herd? Sure, but it's pretty limited. The reality is that vaccination mostly protects YOU - it keeps the infection in the top layer of the respiratory epithelium, ensures to a great degree that you won't be hospitalized for deeper tissue damage.
