So if the vaccinated have an impressed immune systems from over exposure to spike protein and the spike protein isn't actually the only (or main) way sarscov2 infects you (ACE2). Doesn't this guarantee the vaccinated are absolutely fucked as when they are exposed to the wild virus their immune system will only mount spike protein antigens (wuhan variant specific) and basically no immune resistance to the way the virus infects lymphocytes.

Isn't this guaranteed antibody dependent enhancement?

whereas unvaccinated naturally infected will develop a response to the whole virus including whatever mechanism it uses to infect lymphocytes
