This is an old study about adjuvants in mRNA vaccines. They cannot put the adjuvants outside the LNPs because the immune system must be kept calm until the mRNA is inside the cells. Therefore, they tried to add adjuvants inside the LNPs but found out that this is just not necessary: Mammalian cells can sense foreign mRNA with so-called pattern-recognition receptors and alarm the immune system for themselves: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5439223/

There is no old study about adjuvants in mRNA shots because this is the very first time one has been used on humans.
The immune system is not able to react to the shots before they make it into the cell.
Here is a list of adjuvants in the covid mRNA clot shot
This list is not about mRNA vaccines. Adjuvants are for "inactivated vaccines" (dead virus, the upper part of the list) and "subunit vaccines" (artificial virus, lower part) because otherwise the immune system would ignore that junk.
