N1‑methyl‑pseudouridine plays a vital role & is incorporated with higher fidelity than pseudouridine in synthetic mRNAs (payload of the COVID gene injection); Instability of the synthetic mRNAs &

immune responses generated against these synthetic molecules have been rate limiting steps, particularly for therapeutic applications where prolonged expression from the synthetic molecule is desired

‘Instability of the synthetic mRNAs and the immune responses generated against these synthetic molecules have been key hurdles in the adaptation of this technology, particularly for therapeutic applications where prolonged expression from the synthetic molecule is desirable and repeated dosing of the drug product is required1,2. The use of chemically modified bases in synthetic mRNAs is an innovation that has allowed for both an ameliorated immune response to the synthetic molecules and increased protein expression from the mRNA…

It has been shown that the incorporation of pseudouridine (ψ), N1 -methyl-pseudouridine (m1ψ), 5-methylcytosine (m5C), N6-methyladenosine (m6A) and 2-thiouridine (s2U) into synthetic mRNAs results in reduced immune responses and increased protein expression in vivo6–14…

Pseudouridine-modifed mRNAs have been shown to result in reduced activation of 2′-5′-oligoadenylate synthetase (OAS), RNA-dependent protein kinase (PKR), and toll-like receptors…

Furthermore, the presence of m1ψ in synthetic mRNAs show increased translation efficiency in cell-free extracts, multiple mammalian cell lines, and mouse models…

The exact mechanism of how m1ψ enhances translation is not well understood but it has been demonstrated that presence of m1ψ, alone or in combination with other chemical modifications, can alter ribosome transit time on the modified mRNA, and can increase the mRNA half-life by altering the secondary structure of the synthetic mRNA…

Dr. Peter McCullough does his own examination of the vital role of Pseudouridine in synthetic mRNA in the COVID gene injection. See his well written substack below.

‘Natural RNA is made of two purines adenine and guanine and two pyrimidines cytosine and uracil. The replacement of uracil with its ribose ring (uridine) with N-1-methyl-pseudouridine, a synthetic product makes the genetic code for the Wuhan Spike protein better stabilized on lipid nanoparticles, long-lasting, and very efficient in terms of evading cellular destruction and able to undergo repeat reading by ribosomes for continued protein synthesis. Morais et al indicate that both Pfizer and Moderna chose development strategies replacing all uridine units with pseudouridine, making the entire strand completely “unnatural” to the human body. Thus vaccine consultants, companies, and patients unfortunately gambled on how long mRNA would be active within the human body.’
