Yes, but we know the spike protein mutates and most vaccines including Pfizer/Biontech's and Moderna's only target this protein.
Lindy had the foresight to target both the S protein and also the non-mutating N protein that is also common to all Coronaviruses.
I'm not saying that vaccines aimed at the S protein will or will not cope with mutations. Each mutation needs to be tested to determine one way or the other.
