Your body defaults to producing the original antibodies for any future pathogen it sees that seems close — the problem is the vaccines created antibodies narrowly tailored to the spike protein from the original strain (as opposed to natural immunity which targets a more robust cross-section of proteins), so now mudbloods who got the shot before getting the virus keep producing the original antibodies which are less effective or ineffective against strains that show mutations to the spike protein. Look up “original antigenic sin”.
