(OPTIONAL) Up tо 2 pоints оf extrа credit: As we leаrned eаrlier in the quarter, the influenza vaccine and many others you may have gotten typically consist of either proteins representing the pathogen, or an inactivated ("killed") or otherwise "attenuated" (harmless) version of the pathogen. In response to the vaccine, B lymphocytes of your body produce antibodies that bind specifically to the protein or pathogen. This effectively "trains" your immune system to be able to rapidly and powerfully respond if you are exposed to the actual pathogen, thereby protecting you. By contrast, the Pfizer and Moderna developed vaccines for the novel coronavirus SARS-CoV-2 that are instead mRNA vaccines, meaning they consist of mRNA sequences of genes from the coronavirus. Each contains the mRNA that codes for the viral spike protein, a protein on the surface involved in attachment and uptake by the cell. If classical vaccines rely on the injection of a protein in order for the immune system to respond to produce antibodies that bind that protein, what do you think the mechanism is of this mRNA vaccine? Briefly, but clearly describe what happens when an individual is given an mRNA vaccine and how this allows a proper immune response that yields protection. What binds to the virus?
