Ok yes there are viral vaccines that have been given for decades, thus the herd immunity and the low incidence of those diseases. Our older vaccines aren’t 100% effective but because of low exposure because of the low levels of circulating disease they give the impression that people are 100% immune
Experts do feel that the speed advantage is significant. Like being able to respond to a potential new virus (bird flu). They are speaking out about it currently. I don’t know the logistics of mRNA could be developed for flu, but as it is we develop our flu based on what happened in other parts
Of the world 9-6 months ago, if we could cut that time lapse down to the strains that happened at the end of the flu season that could be significant. Anecdotally people talk about I got the flu shot but I still got the flu, there might be ways to mitigate that
Assuming what we’ve been doing is good enough doesn’t mean we don’t have the power to make it better
There also people who can’t get the flu shot and others as it is currently developed due to allergies, novel vaccine technologies might help them so they don’t have to rely solely on herd immunity
Sure, keep researching it and using it where there’s an advantage. I’m not against that.
