    In a study of 275 patients, S- and N-antibody titers were analyzed to assess their correlation with clinical features of long COVID.

  • 3

    Vaccinated patients had significantly higher S- and N-antibody titers compared to unvaccinated patients, indicating the impact of vaccination.

  • 4

    Lower S-antibody levels were linked to cognitive impairment and reduced quality of life in long COVID patients.

  • 5

    N-antibody titers were influenced by gender and time since infection, reflecting immune responses in long COVID management.
