Nope, I agree that a big issue is the “vehicle” (spike protein) so the same clots caused from all jabs can be an hazard on Sputnik too (even if you can see the results in San Marino, not a single problem and all of them Sputnik jabbed). The main issue with Moderna/Pfizer/Johnson is the totally experimental technology (mRNA). In a few words, they are experimenting with billions of guinea︀ pigs.
