On the contrary, J&J and AZ are adding a step.

Pfizer/Moderna inject the mRNA into the cytosol where it makes the protein.

J&J and AZ inject an adenovirus, which attacks the cells, gets into the cells, then attacks the nucleus. It injects the spike protein DNA into the nucleus. The nucleus makes the mRNA, that gets carried out into the cytosol, and then it makes the spike protein, just like the Pfizer and Moderna.

Anyone who thinks the J&J/AZ are less invasive are completely clueless. As to which is safer, if I had to guess it would be P/M, because of the fewer steps, less invasive nature and much less likely chance of altering the DNA.

However, only data could really tell us, and that is being hidden.
