Abstract Here we conducted a multicenter open-label, randomized phase 2 and 3 study to assess the safety immunogenicity of severe acute respiratory syndrome coronavirus (SARS-CoV-2) Omicron-specific (BA.1/B.1.1.529), monovalent, thermostable, self-amplifying mRNA vaccine, GEMCOVAC-OM, when administered intradermally as booster in healthy adults who had received two doses BBV152 or ChAdOx1 nCoV-19. GEMCOVAC-OM was well tolerated with no related serious adverse events both 3. In 2, compared...

Selecting a booster vaccine strategy that generates cellular immune breadth is crucial for effectively recalling reservoirs upon infection with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) variants. This post hoc analysis from multicentre, randomized phase 3 study (CTRI/2022/10/046475) compared the induced by self-replicating mRNA (samRNA) GEMCOVAC-OM, encoding Omicron B.1.1.529 Spike protein, adenovector ChAdOx1 nCoV-19, Wuhan variant when administered as booster....

Phagemid-based expression of cloned genes fused to the gIIIP coding sequence and rescue using helper phages, such as VCSM13, has been used extensively for constructing large antibody phage display libraries. However, randomly primed cDNA gene fragment libraries, this system encounters reading frame problems wherein only one 18 phages translated foreign peptide/protein phagemid-encoded gIIIP. The elimination carrying out-of-frame inserts is vital in order improve quality In study, we designed...

Recently, mRNA has gained a lot of attention in the field vaccines, gene therapy, and protein replacement therapies. Herein, we are demonstrating comprehensive approach to designing, cloning, characterizing an antigenic cassette for development vaccine COVID-19. The encoding spike SARS-CoV-2 Omicron variant (B.1.1.529) was designed using databases, characterized by

Background/Objectives: The nucleic acid-based product (NAP) portfolio is expanding continuously and provides safer curative options for many disease indications. Nucleic products offer several advantages compared to proteins virus-based products. They represent an emerging field; thus, their quality control regulatory landscape evolving ensure adequate safety. Next-Generation Sequencing (NGS) mostly recommended NAP identity testing, we are leveraging its application impurity profiling....

Abstract Recently, genomics has gained a lot of attention in the field bio-therapeutics, vaccines, and gene therapy. We have developed robust pipeline for establishing mRNA vaccine portfolio to address current pandemic endemic COVID-19, infectious diseases, cancer. designed assembled approximately 4000 base pair DNA encoding spike protein SARS-CoV-2 Omicron variant (B.1.1.529) using overlapping oligo-based PCR assembly. Further, we cloned this fragment into self-amplifying platform prepared...
