Covid boosters were being given 20 years before Covid existed?
Some anti-Covid-vaxxer yanked that "24 years" number out of their rectum, because it's still over 20 years in the future from when boosters started being administered. 
I could, with the same evidence - NONE - claim that Covd boosters add 30 years to every recipients life. But I'm not that stupid and dishonest.
What stupid clickbait claptrap!
Right. Line up the illegals and give them all the shots. Or they can go back where they came from. Can't be too careful, right?

Seriously, though, I, in typical fashion ground back to the study cited and linked in the SLAY article this post was based on: (Link provided so you can read it if you are interested)
Effectiveness of the Coronavirus Disease 2019 (COVID-19) Bivalent Vaccinehttps://www.medrxiv.org/content/10.1101/2022.12.17.22283625v1.full.pdf.
I found numerous statements to the effect that their study of vaccine efficacy was complicated by individuals with prior infections of COVID and who had thus acquired
natural immunity, regardless of the variant they had caught.
However, I found no indication that the study considered reduced lifespans, nor any mention of that possible aspect in the study. The linked study did not support the contention of the article. If I missed a link, let me know.
(This is why I like to go back to the prime source, rather than rely on commentary).
I'm a fan of Pam Geller, she points out a lot of stuff in a very timely fashion, but in the words of Ronald Reagan: "Trust, but verify."
Maybe SLAY linked the wrong study.
