"never promised mucosal immunity" Promising something and providing something aren't the same thing. I might have missed it in https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7733922/ but where does it say that no mucosal immunity is provided by the current generation of vaccines. "infected and have long recovered with sterilizing immunity that is better than symptom-reduction from non-sterilizing vaccines" The article you link to here doesn't make this strong a claim. It says "at least as good" not "better" and references a single study from Israel. I don't think based upon the evidence presented your summation is supported. |

> Whilst we feel that current vaccines are excellent for reducing the risk of hospital admission and disease, we propose that research be focused on vaccines that also induce high and durable levels of mucosal immunity in order to reduce infection of and transmission from vaccinated individuals.
Note the "high and durable" statement. Antibody levels in the upper respiratory tract need to be high enough to protect against infection, not incidental presence from serum antibodies.
SAGE is asking for research, since current vaccines do not provide this. There is a third article on intra-nasal vaccines, saying the same thing. It is also common knowledge in the medical profession.
This is why the CDC now recommends testing of vaccinated people, https://www.webmd.com/lung/news/20210729/cdc-reverses-guidan...
> Even if they’re not showing symptoms, fully vaccinated people should “get tested 3-5 days after exposure to someone with suspected or confirmed COVID-19 and wear a mask in public indoor settings for 14 days after exposure or until they receive a negative test result,” the agency’s website says. The CDC previously said fully vaccinated people didn’t need testing after exposure unless they showed symptoms. “Our updated guidance recommends vaccinated people get tested upon exposure regardless of symptoms,” CDC Director Rochelle Walensky, MD, told The New York Times in an email. “Testing is widely available.”
