r/Health – The COVID Vaccine We Need Now May Not Be a Shot: Nasal vaccines may be the best way to prevent infections long term, because they provide protection exactly where it is needed to fend off the virus: the mucosal linings of the airways, where the coronavirus first lands.

i have read some scientists before speculating that the best results might be from people getting a vaccines shot first followed by nasal spray after.

it would be great if there was a nasal or oral vaccine to make it easier to give, less medical bottle necks of special vials or neeles or trained vaccinators. also easier for thsoe with needle phobia getting whatever more % of the world population protected.
