Knowing nothing about biotech – if Moderna and Pfizer were working from the same sequencing data, why would their resulting vaccine mRNA sequences be different? Even slightly?
Edit: I guess what I'm asking is: presumably these vaccines both target the spike protein. Do both of these sequences express the same protein? Or is there a "close enough!" thing in the immune system, where it can be a little different and still be targeted by the immune system?
