Summary:

- The article reports on a study conducted by researchers at the University of California San Diego, which found elevated levels of SARS-CoV-2 spike proteins in the blood of some individuals nearly two years after receiving COVID-19 vaccination.
- The study, which has not yet been peer-reviewed, suggests that the spike proteins may persist in the body longer than previously thought, potentially raising concerns about the long-term effects of the vaccines.
- The researchers emphasize the need for further research to understand the implications of these findings and to determine whether the persistent spike proteins pose any health risks to vaccinated individuals.
