Repeated COVID-19 vaccination weakens the immune system, potentially making people susceptible to life-threatening conditions such as cancer, according to a new study.
Multiple doses of the Pfizer or Moderna COVID-19 vaccines lead to higher levels of antibodies called IgG4, which can provide a protective effect. But a growing body of evidence indicates that the “abnormally high levels” of the immunoglobulin subclass actually make the immune system more susceptible to the COVID-19 spike protein in the vaccines, researchers said in the paper.
They pointed to experiments performed on mice that found multiple boosters on top of the initial COVID-19 vaccination “significantly decreased” protection against both the Delta and Omicron virus variants and testing that found a spike in IgG4 levels after repeat Pfizer vaccination, suggesting immune exhaustion….
