For many drugs, the dosage is scaled depending on the size of the patient.

But for vaccines, this seems not to be the case. It not obvious why a larger person shouldn't be given a larger dose?

Also, an obese person is likely to have more fat cells in the muscle where the vaccine is injected. Would the vaccine be absorbed in the fat cells and diluted? After all, the mRNA vaccines are encased in lipid (fat) shells.
