Question

1. What are mRNA vaccines and how do they work? 2. For the two COVID19 mRNA vaccines (Pfizer and Moderna vaccines) a. What "protein products/viral antigen" do they encode to induce an immune response in our body? b. How are they delivered into the cell? (Not injection site, but how are the mRNA packaged to ensure their delivery into the target cell?) 3. What are adenovirus-based vaccines and how do they work?

Step 1

mRNA vaccines are a type of vaccine that use a small piece of the pathogen's genetic material, called messenger RNA (mRNA), to instruct cells in the body to produce a harmless protein that triggers an immune response. This immune response helps protect against Show more…
