Summary:
The article by Palmer and Bhakdi examines a study by Bansal et al. that identified the presence of SARS-CoV-2 spike protein in exosomes for up to four months post-vaccination with the Pfizer mRNA vaccine. This prolonged expression raises concerns about potential sustained inflammation and organ damage in vaccinated individuals. The authors discuss previous findings, notably those by Ogata et al., which suggested a shorter duration of spike protein expression. They highlight the methodological differences between studies, particularly in the detection of spike protein and its fragments, which may account for the discrepancies in findings. The authors conclude that the long-lasting presence of spike protein, either from mRNA or the protein itself, could lead to chronic inflammatory responses, thus necessitating further investigation into the implications for vaccine safety and efficacy.
