Seriously? Tell "her" to open her eyes and use common sense. If at this point anyone can't see that this "vax" is causing more harm than good, then they're not worth the time talking to. Tell her to look at Israel and Gibraltar, two of the most heavily vaxed countries on the planet.
A study from an "official" agency? Good luck. They're the ones pushing the scam.
They can keep telling themselves this all they way, but it's not going to help them in the end.
