Vaccine composition for varicella zoster virus
A recently granted patent (Publication Number: US11918644B2) discloses a vaccine composition designed to target the varicella zoster virus (VZV) by utilizing a messenger ribonucleic acid (mRNA) encoding specific glycoproteins. The composition includes a lipid nanoparticle with precise proportions of ionizable cationic lipid, neutral lipid, cholesterol, and polyethylene glycol (PEG)-modified lipid. The mRNA in the vaccine composition can be chemically modified to enhance its efficacy, with options such as pseudouridine, N1-methylpseudouridine, and other modifications listed in the claims.
Furthermore, the patent details variations in the lipid nanoparticle composition, specifying different percentages of cationic lipid, neutral lipid, cholesterol, and PEG-modified lipid. The specific amino acid sequences of the VZV glycoproteins targeted by the vaccine are also highlighted, including mutations like Y569A in the VZV gE protein. The patent emphasizes the use of chemically modified mRNA, such as N1-methylpseudouridine, to encode the VZV glycoproteins, enhancing the vaccine’s potential effectiveness. Overall, the patent provides a detailed framework for a vaccine composition targeting VZV, utilizing innovative mRNA and lipid nanoparticle technology for improved immunization strategies.
