In reply to Johnson + Johnson vaccine can someone explain how, posted by Phillipa on May 6, 2021, at 9:12:37
Unlike the mRNA vaccines (Pfizer; Moderna), vector-based vaccines (Johnson & Johnson; AstraZeneca), are produced by transplanting a piece of the SARS-CoV-2 DNA that encodes for the coronavirus antigen into a harmless adenovirus (like the common cold). The adenovirus is the vector. The transplanted DNA encodes for a piece of protein that is normally found on the spikes on the surface of the coronavirus. When the vector virus penetrates a healthy body cell, it releases the coronavirus DNA into the main cytoplasm (as opposed to the nucleus). There, the cell is instructed by the DNA to build its own spike proteins and erect them on the surface of its outer cell membrane. This is in contrast to the mRNA vaccines, which instruct the body cell to manufacture the antigen protein, but then releases it into the blood stream instead. With both types of vaccines, the immune system is provoked into producing antibodies in response to the presence of the spike protein antigen.
