A group of German scientists released the research as a preprint in July, but it attracted little notice until Science Immunology formally published it on Dec. 22. It is not clear if the new interest comes because the paper has passed peer review or because Covid’s continued surge is troubling researchers.
Like many other scientists, the German researchers measured anti-spike-protein antibodies that people produce after Covid vaccination. Both mRNA and DNA jabs cause the body’s cells to produce spike proteins like those on the surface of the coronavirus.
Those proteins then cause the immune system to make antibodies – Y-shaped proteins which attach to pieces of the spikes. In the case of a real coronavirus infection, the vaccine-generated antibodies stick to the surface spikes on the coronavirus and keep it from attaching to our cells.
Confirming hundreds of similar studies, the German researchers found that levels of a crucial antibody called Immunoglobulin G, or IgG, rose dramatically after the second and third mRNA doses. Those increased antibodies have been the triumph of the mRNA vaccines.
Then the German scientists took a step other researchers had not.
