[Vaccination immunology in SARS-CoV-2].

Area of Science:

• Immunology
• Virology
• Infectious Diseases

Background:

• The duration of adaptive immunity following SARS-CoV-2 infection or vaccination remains incompletely understood.
• Significant progress has been achieved in characterizing the B-cell and T-cell responses that underpin protective immunity.

Purpose of the Study:

• To review and synthesize current data on SARS-CoV-2 re-infection.
• To present key findings on B-cell and T-cell immunity after both infection and vaccination against SARS-CoV-2.

Main Methods:

• Literature review of studies investigating SARS-CoV-2 re-infection.
• Analysis of data from immunological studies focusing on B-cell and T-cell responses.
• Synthesis of information on immunity derived from both natural infection and vaccine administration.

Main Results:

• Key data on the dynamics of re-infection are presented.
• Evidence regarding the characteristics of SARS-CoV-2 specific B-cell responses (e.g., antibody production, memory B cells) is summarized.
• Information on T-cell mediated immunity (e.g., cytotoxic T lymphocytes, helper T cells) following infection and vaccination is detailed.

Conclusions:

• Advances in understanding SARS-CoV-2 B- and T-cell immunity provide insights into protection duration.
• The presented data aids in evaluating the robustness and longevity of immunity after infection and vaccination.
• Further research is warranted to fully elucidate the long-term protective immunity against SARS-CoV-2.
