Pfizer takes COVID jab with ‘enhanced’ spike protein into phase 2

pharmaphorum

Pfizer and BioNTech have started a mid-stage trial of a new version of the COVID-19 vaccine based on a version of the spike protein that they hope will offer greater and broader protection against SARS-CoV-2 variants. Clinical data show strong neutralising antibody responses against Omicron BA.1,

Drug made from pig intestine helps escape the “trap” of clot-causing immune response

Scienmag

When the body attempts to fight off an infection, immune cells called neutrophils may shoot out spider web-like networks of toxic proteins to help contain the invaders.

Experimental COVID-19 vaccine offers long-term protection against severe disease

Medical Xpress

In 2021, a group of scientists led by researchers at the University of North Carolina at Chapel Hill, Weill Cornell Medicine and NewYork-Presbyterian reported that the Moderna mRNA vaccine and a protein-based vaccine candidate containing an adjuvant, a substance that enhances immune responses, elicited durable neutralizing antibody responses to SARS-CoV-2 (..)

New research will allow convenient investigation of human innate immune response to viral infections

Scienmag

(Boston)–Researchers from Boston University School of Medicine (BUSM) report the formation of human cells containing a green fluorescent protein or GFP (one of the most important proteins in biology and fluorescence imaging) genetically fused with two interferon stimulated genes (ISGs), namely Viperin and ISG15.

A protein-based COVID-19 vaccine that mimics the shape of the virus

The Pharma Data

Food and Drug Administration were based on mRNA, more conventional protein-based vaccines have also shown promise in clinical trials. Most train the immune system to recognize the RBD, a peptide that is the portion of the SARS-CoV-2 spike protein that binds to the ACE-2 receptor on host cell surfaces. bioRxiv [Preprint].
