retard here needing some help from mRNA-anon

been following this mRNA, spike-protein, antigen stuff on the interwebs, which explains how mRNA vaccine technology is being used to target a specific gene sequence, such as a specific virus or variant.

Is it possible the mRNA vaccine technology can be made to stimulate the development of non-specific antigens, and essentially super-power the innate immune system with broad coverage against all viruses? Can this be done? Has it been done?

Is this another "Trump you beautiful bastard" moment?
