Well, they are obsolete. If there was a vaccine that could bring Omicron to R < 1 among those who didn't yet have the latest variant, there would be plenty of demand. Especially if it had mild enough side effects for continued regular shots to be preferable to occasional reinfections. As it is, a second Omicron infection after 3 shots seems to be 1-2 days of sniffles while each additional shot is 3 solid days of fever/puking/misery. Common sense suggests not taking something that makes you quite sick again and again. Mind you, someone with no preexisting immunity or one natural infection would do well to get 3 shots rather than risking severe disease or lingering after effects. But how many people in the world are in this position anymore? Everyone willing and able has got the shots and the rest have been exposed multiple times and either developed effective immunity or succumbed to the disease. I can see some corner cases like babies and immunocompromised, but that's not a lot of doses. Hopefully they will have access to stronger / less unpleasant vaccine before long.
