«This customized mRNA is given a special coating that will aid its entry into cells.
In the case of the Pfizer/BioNTech and Moderna vaccines, this coating consists of liposomes and a chemical called polyethylene glycol (PEG).
PEG has never been used before in an approved vaccine, but is found in many drugs that have triggered anaphylaxis — a potentially
life-threatening reaction that can cause rashes, plummeting blood pressure, shortness of breath, and rapid heartbeat.
So when severe allergy-like reactions occurred in at least eight people who received the Pfizer-BioNTech vaccine during a 2-week period in December 2020, many scientists naturally suspected PEG.»
