Well, this is an interesting one. Social Security just had its biggest drop in beneficiaries in its history and it was sudden. When the data was first released, most analysts thought it was due to the DOGE cuts but those haven't been implemented yet. It appears that there's been a sudden surge of old people dying. Of course old people die all the time, but it's usually at a constant rate, with seasonable ebbs and flows, but this was large and unexpected.
Could it be the vax? Sure, but it begs the question of why so many at once and why now?
