Cool, so the spike protein "factory" creates facsimiles of the actual SARS-CoV-2 spike protein, which then becomes a trigger to the immune system to create antibodies for that specific virus/spike protein combo. The mRNA approach to vaccines seems to be a leaner, meaner, 2.0 version wherein instead of injecting a virus ut totum the vaccine-development-wizards have developed it to use just enough of the original virus code to trigger the immunological response, bolstering our defenses, and thereby increasing resistance to the thing "in the wild." Would this apply to other coronaviruses, such as "common cold" type vaccinations? Were there specific discoveries in 2020 that will open the floodgates to better influenza protection? </rhetorical> These types of responses are really helpful, and help me to get back into a rational framing of the subject - rather than fielding psychological noise from headlines and sub-informational news pieces.
