But is it really the case that rumors of clotting are merely that, mere rumors? An efflorescence of dark humor in a trying time? Dr. John Campbell has been following the story, and interviewing doctors, scientists, and embalmers:
In this repeat interview with Major Tom Haviland, who has spoken to and polled embalmers at morticians’ conventions, we learn that while the stories told and evidence collected by embalmers working on dead bodies (preparing them for internment) are alarming, scientists and government funders have shown remarkable restraint in following up on clues.
The clots being found after the rollout of the various “vaccines” are not just small, easy to tear. They are large, “tough and rubbery.”

However, the mainstream of the medical profession takes pains to debunk these stories every now and then, dismissing them as tall tales, or as almost anodyne, quite common before and after the pandemic, contrary to the testimony of Haviland.
Note that Haviland and Campbell are not talking about microclotting. Nor is Haviland referring to “chicken fat clots,” which are small, yellow, and have been observed for a very long time. Haviland is on track of an even more alarming trend, which features clots of sometimes gruesome length.
Be careful in choosing an emoji to accompany your “clot shot” epithet.
