Leading innovators in coronavirus vaccine components

Pharmaceutical Technology

The key component in all vaccines is one or more active ingredients made from viruses or bacteria, also called antigens, which generates an immune response. The active component of the Pfizer-BioNTech vaccine tozinameran, contains the genetic code for the coronavirus spike protein, inside a lipid (fat) capsule.

What Do We Really Know About Macrophage Programming?

XTalks

Macrophages are white blood cells that specialize in the detection, phagocytosis and destruction of bacteria and other harmful organisms. In other words, when fighting bacteria, the macrophages are programmed to be pro-inflammatory. They found a protein called Rspondin3, which is released at high levels during inflammatory injury.

Pfizer and Valneva Issue Update on Phase 3 Clinical Trial Evaluating Lyme Disease Vaccine Candidate VLA15

Pfizer

This investigational multivalent protein subunit vaccine uses an established mechanism of action for a Lyme disease vaccine that targets the outer surface protein A (OspA) of Borrelia burgdorferi, the bacteria that cause Lyme disease. OspA is a surface protein expressed by the bacteria when present in a tick.

Merck Announces Positive Topline Results from Two Additional Phase 3 Adult Studies Evaluating V114, Merck’s Investigational 15-valent Pneumococcal Conjugate Vaccine

The Pharma Data

Immune responses following vaccination with PNEUMOVAX 23 (month 13) were comparable in both vaccination groups for the 15 serotypes in V114. Results from both studies are based on opsonophagocytic activity (OPA) responses – a measure of vaccine-induced functional antibodies. among adults 65 years of age or older.

Research Roundup: Different Antibody Responses to COVID-19 and More

The Pharma Data

People with severe COVID-19 have low proportions of antibodies that target the spike protein. In milder cases, the antibodies seem to do a better job of binding to the spike protein. The spike protein binds to the ACE2 receptor on human cells, which allows the virus to enter the cell.
