they're already trying out nasal vaccines: "India has rolled out a nasal drop vaccine, iNCOVACC [...while....] China authorised the use of the world’s first inhaled vaccine, Convidecia Air, [....] delivered through a puff of air from a nebulizer that is then inhaled by mouth..." - https://asianews.network/india-rolls-out-nasal-vaccine-as-it-prepares-for-rise-in-covid-19-cases/
There was a big hullabaloo in the media several years ago about development of a nasal vaccine for the flu and for rhinoviruses. Some time later it was evident that this was just paid advertisement. These vaccines did not work.
so.... either 'they' hope that we forgot, or it is actually a new type of product that might work, after having been extensively studied and tested (slight undertone of sarcasm).
Very few people understand science. I estimate thar only 1 in ten thousand of biologist and medical doctors understand that PCR tests of the nasopharynx or otopharynx secretion tell us much more about the quality of the air wy breathe than about the infection.
which, in most of the populated areas around the world, is heavily polluted by exhaust fumes, industrial waste and agricultural poisoning et.al. TQ for clarifying.
