I remember reading that the ideal vaccine location for respiratory illness would be a nasal and lung aerosol so there would be a strong local immune response making it harder for any future infections to replicate effectively. Don’t know if that is still being looked at.

It leads with this: > Vaccines that are injected into arm muscles aren’t likely to be able to protect our nasal passages from marauding SARS-CoV-2 viruses for very long It might be true, but I would have liked to read more. It's pretty easy to envision a case where that's not true, and the immune system doesn't really care where the vaccine was given.
