Ethylene glycol is poisonous to humans and other animals. Its metabolism produces
calcium oxalate, which crystallizes in the brain, heart, lungs, and kidneys, damaging them; depending on the level of exposure,
accumulation of the poison in the body can last weeks or months before causing death, but death by
acute kidney failure can result within 72 hours if the individual does not receive appropriate medical treatment for the poisoning.
So maybe you are somewhat safe if you only get one jab. Seems like the more jabs people get, the sicker they get.
