Does either pfizer or moderna have fewer side effects ? what i mean to ask is do people react less to one vaccine than the other?

A paper published by NIH reports both vaccines can cause various adverse effects, but these rxns are reported to be less frequent in the Pfizer/BioNTech vaccine than Moderna vaccine. However, the Moderna vaccine is easier to transport & store because it is not as temperature sensitive. (https://pubmed.ncbi.nlm.nih.gov/33629336/) I wish you well with your health!
