The mRNA vaccines against SARS-CoV-2 work to protect us against COVID-19 by a. causing our cells to make a weakened version of the virus to \"train\" our immune system to recognize and attack the virus. b. causing our cells to express a viral protein to \"train\" our immune system to recognize and attack the virus. c. providing genetic sequences that encode antibodies against the virus so our immune cells can make the protective antibodies. d. causing our cells to make interferon, a natural protein that activates our immune system.

What are mRNA vaccines and how do they work? For the two COVID-19 mRNA vaccines (Pfizer and Moderna vaccines), what "protein products/viral antigens" do they encode to induce an immune response in our body? How are they delivered into the cell? (Not injection site, but how are the mRNA packaged to ensure their delivery into the target cell?) What are adenovirus-based vaccines and how do they work?

Several different types a vaccines have been made to immunize people against infection by the new coronavirus. One category of vaccines are called Messenger RNA (mRNA) vaccines. These vaccines contain nothing except the Messenger RNA for just one of the proteins that the novel coronavirus makes. Specifically, a protein called the spike protein which is on the outside of the coronavirus particle. This is one of the proteins that your immune system responds to when you become infected by the coronavirus. Considering this information, which of the following is true? A. The vaccine Messenger RNA use translated into a protein by the coronavirus ribosomes B. The vaccine Messenger RNA must be transported into the nucleus before it can be translated C. The vaccine Messenger RNA has a ribosomal binding site near its three prime end D. The vaccine Messenger RNA has a ribosomal binding site near its five prime end E. The vaccine Messenger RNA is transcribed into a protein by your ribosomes

Antigens are foreign proteins that invade the systems of organisms. Vaccines function by stimulating an organism's immune system to develop antibodies against a particular antigen. Developing a vaccine involves producing an antigen that can be introduced into the organism being vaccinated and which will trigger an immune response without causing the disease associated with the antigen. Certain strains of bacteria can be used to produce antigens used in vaccines. Which of the following best explains how bacteria can be genetically engineered to produce a desired antigen? A. The gene coding for the antigen can be inserted into plasmids that can be used to transform the bacteria. B. The bacteria need to be exposed to the antigen so they can produce the antibodies. C. The DNA of the antigen has to be transcribed in order for the mRNA produced to be inserted into the bacteria. D. The mRNA of the antigen has to be translated in order for the protein to be inserted into the bacteria.
