Stanford Medicine investigators have unearthed the biological process by which mRNA-based vaccines for COVID-19 can cause heart damage in some young men and adolescents — and they’ve shown a possible route to reducing its likelihood.
Using advanced but now common lab technologies, along with published data from vaccinated individuals, the researchers identified a two-step sequence in which these vaccines activate a certain type of immune cell, in turn riling up another type of immune cell. The resulting inflammatory activity directly injures heart muscle cells, while triggering further inflammatory damage.
