Do you have any studies to share that confirm this claim? As far I am aware the new variants evolved from regions that were not highly vaccinated like South Africa.
Omicron was considerably more virulent than flu - the risk of getting an infection is also a function of prevalence.
But I don't think we'll get any better vaccine soon the medical community appears to be too stubborn for this to happen.
I'm not arguing that vaccines can't or shouldn't be much better. Just that they actually were considerably good if we take everything we should into account.
