the Pfizer-BioNTech COVID-19 Vaccine for use in children 5-11 years of age uses tromethamine (Tris) buffer
Tromethamine (Tris) is a blood acid reducer which is used to stabilize people with heart attacks. Here are known side effects: Respiratory depression, local irritation, tissue inflammation, injection site infection, febrile response, chemical phlebitis, venospasm (vein spasms), hypervolemia, IV thrombosis, extravasation (with possible necrosis and sloughing of tissues), transient decreases in blood glucose concentrations, hypoglycemia, and hepatocellular necrosis with infusion via low-lying umbilical venous catheters

Tris is used in many medications and vaccines as acid buffer - to stabilize the medication, not to stabilize the patient. Tris is toxic, it replaces a less toxic stabilizer in the vaccines for adults, and they have done it to prolong the shelf life of the vaccine. The heart attack angle is a red herring.
This is the kind of stuff I come here for. Thanks
