mRNA has URACIL in its composition.
cmRNA (chemically modified mRNA) has PSEUDOURIDINE included in the genetic code.
The definition used in genetics is very clear:
"cmRNA is mRNA that has been modified through the substitution of chemically modified bases for normal bases, such as pseudouridine for uridine."
The Pfizer and the Moderna vaccines are cmRNA vaccines, not mRNA vaccines. Uracil has been replaced 100% with Pseudouridine. This catastrophic modification was made by a most incompetent chemist (K. Kariko) in 2008, who paid no attention to the stereochemistry (chirality/isomeric properties) of the entire operation. She had no knowledge of the legacy of the most important chemist of all time, Linus Pauling (Nobel prize winner), who stated that the chirality of the molecules represents the most important aspect of chemistry. It's one thing to perform such an experiment in some laboratory, and something else to inject Pseudouridine into the bodies of billions of people with no genotoxicity studies.

Extract from the EMA report on Comirnaty (Pfizer vaccine): "Genotoxicity: No genotoxicity studies were provided. This is acceptable because the components present in the vaccine formulation are lipids and RNA which should not have genotoxic potential (EMA, 2021) ”.
From a scientific and safety point of view, this can be seen as irresponsible.
