mRNA vaccines: Moderna, Pfizer Adenovirus vaccines: Johnson & Johnson, AstraZeneca, Sputnik V How J&J is different from mRNA The Johnson & Johnson vaccine is not an mRNA vaccine (like Pfizer and Moderna). All three vaccines deliver genetic material to your cells: mRNA vaccines deliver mRNA, and Johnson & Johnson delivers DNA. Another difference is the delivery method used – either a little enclosure made of fat surrounds the genetic material, or in the case of Johnson & Johnson, an adenovirus carries it. But the end result is the same: both the mRNA vaccines and the Johnson & Johnson vaccine help your body to develop antibodies against the coronavirus spike protein.
I am getting caught up on this quote
"Once the adenovirus [and DNA] gets inside your cell, the spike protein gets manufactured by your own cellular mechanisms," explains infectious diseases expert James Lawler, MD, MPH.
Would you describe J&J as a DNA shot?
Yes.
