You kind of answer your own question. Why do they test on animals? What purpose do other mammals serve? They are a good facsimile for humans. Do you think, in modern history, any drug has ever been released that killed all the animals in trials? Has any drug ever been released and forced into use the way the jab is, with no liability for anyone involved?

There are 2 issues here. “Leaky” vaccine is what kills the animals. Measles is a “perfect” vaccine. Covid is “imperfect” or leaky. https://www.healthline.com/health-news/leaky-vaccines-can-produce-stronger-versions-of-viruses-072715

It creates a feedback loop in the vaccinated, because they still spread the virus, but the symptoms are messed with. What this looks like to the outward observer is ever increasing rates of transmission, and more deadly cases of covid, in the vaccinated. More and more and more breakthrough cases. The higher the density of vaccinated, the faster this process occurs.

Now you look at covid cases in Israel and Gibraltar, right now, and tell me that what we are seeing isn’t leaky vaccine. It’s happening right now.

The second issue is the clotting. This is a different problem, and seems to be related to the chemistry creating micro clots. Acute in some people requiring hospitalization. It’s the non acute cases that we should be worried about. All of the people who didn’t have immediate cardiac issues. What about 20 years from now?

Watch Israel. They are the Petri dish. We can assume whatever happens there to there vaccinated people, is going to happen here. Soon too. Winter is approaching.

Took them 2 years to pull thalidomide, and that made women have flipper babies. Took years to pull phen-fen, and that caused heart failure. It’s happened a dozen times in the last 50 years. Would it really surprise you if that happened again?
