This study developed a new technology using tiny fluorescent diamonds to track where aluminum adjuvants (a component in vaccines) travel in the body and how long they stay there. Researchers found that these aluminum particles, which are used to boost immune response in vaccines, can move from the injection site to lymph nodes, the spleen, liver, and brain, where they accumulate over time. This tracking technology could help scientists better understand whether long-term exposure to these particles might cause health problems.
