Repeated mRNA Vaccination May Hamper Recovery From COVID-19: Study
Published on January 24, 2024
Taking multiple mRNA vaccines can end up raising the levels of a specific antibody that is linked to a reduced capacity of the immune system and “poor clinical outcomes of COVID-19,” according to recent research. The preprint study, published in MedRxiv on Jan. 18, looked at the effects of Moderna and Pfizer mRNA COVID-19 vaccines as well as Novavax COVID-19 shots on IgG4 antibody levels in the human body. IgG4 is a subclass of Immunoglobulin G (IgG) antibodies, which are proteins released by the immune system to fight against foreign substances. There are four subclasses of IgG antibodies—IgG1, IgG2, IgG3, and IgG4. Out of these, IgG4 is the least prevalent, accounting for around 0 to 5 percent of total IgG....
