It sure would have been nice if there was a quality intranasal vaccine that the government could have shipped to each household instead of the insane goose chase that was trying to get vaccine appointments.
There’s some theory that this would have been the best approach so everyone has a lot of immunity all at once and the virus dies out (barring some other non-human reservoirs).
It’s possible an entire population with varying immunity allowed there to always be some reservoir out there.
But good luck immunizing everyone, especially at the same time.
I suspect the excessive emphasis on fomite transmission of covid-19 was caused by too many decision-makers (re-)watching Contagion as their “Idiot’s Guide To Handling a Pandemic”.
Some would, but it definitely is a bigger ask of people to have something injected into their bloodstream by a medical professional rather than to just spray something in their nose. I think it'd win over a substantial chunk of the vaccine-hesitant.
Have you spoken to any vaccine-hesitant? Almost none of them are vaccine-hesitant because they don't like the idea of a needle in their arm; a nasal delivery method would have almost no measurable effect on voluntary uptake.
It IS a more traditional vaccine, though, and less scary because of that. And this is not being pushed to the fullest extent of the law (and a bit above it I think, but nobody can really prove that).
I don't think they'd say it's because they don't like the idea of a needle in their arm, but for a lot of them, I think it's a significant contributing factor.
