The part that this 2+ year old study doesn't take into consideration Omicron vaccinations. You've been vaccinated against Omicron, like a normal, sane person, haven't you? At the time this was written, they were only using original strain vaccinations. Where I am, in the present, you can't even get those any more, they're so far behind.

Or, are you an idiot, and basing decisions off of out of date papers? Because it seems like you might be.

I bet you don't even understand how flu vaccines change.
