Rhonda explains that a study found that a high dose of the Pfizer BioNTech vaccine given to rats caused the lipid nanoparticle containing mRNA to be found in other organs. However, a lower dose given to mice did not show the same result. Furthermore, the remnants of the lipid nanoparticle found in other organs may have been chopped up by immune cells and taken to other tissues for recycling. The study also found that the spike protein from mRNA vaccines or the Johnson and Johnson vaccine is unlikely to cause damage to other organs.
