From Steve Kirsch substack...

The FAA has very quietly tacitly admitted that the EKGs of pilots are no longer normal. We should be concerned. Very concerned.
After the vaccine rolled out, the FAA secretly widened the EKG parameter range for pilots so they wouldn’t be grounded. It looks like the vax gave at least 50M Americans heart damage.

TLDR version -  In Oct, 2022, the FAA relaxed EKG regulations, probably because too many pilots were failing due to mRNA damage.

Last year I glanced through the Thailand and Puerto Rico studies he references and I've seen other studies with similar results (30% to 70% have heart damage).

Kirsch is already a controversial public figure so his estimate is quite conservative.  Some critical thinking may lead you to a more accurate estimate.  I predict the Biden administration will stonewall the real issue and foist blame on false "uncontrollable factors".

I found this part particularly interesting:

nursing homes have lost up to 33% of their
residents in 12 months where before they were
losing only 1 or 2% a year...

I was unable to find even a single
nursing home where the all-cause mortality
dropped after the vaccines rolled out

In late 2019, I was lucky enough to stumble upon a German television interview with Geert Vanden Bossche which spurred me to further research on mRNA vaccines, which led me to avoid them in 2021.
