Immune response in COVID-19: what is next?

Area of Science:

• Immunology
• Virology
• Public Health

Background:

• COVID-19 pandemic has persisted for over two years, significantly impacting global lifestyles.
• Understanding SARS-CoV-2 immunity and its regulation is crucial for managing the ongoing pandemic.
• The review synthesizes current knowledge on virus evolution and disease manifestations.

Purpose of the Study:

• To review SARS-CoV-2 mutations and evolving COVID-19 disease manifestations.
• To analyze alterations in immune responses, including innate, humoral, and cellular immunity.
• To compare vaccine properties and discuss therapeutic strategies for COVID-19.

Main Methods:

• Literature review of current scientific publications.
• Analysis of virus mutations and their impact on disease.
• Comparative assessment of vaccine-induced immunity.
• Discussion of therapeutic interventions: antibody treatments, antivirals, and inflammation control.

Main Results:

• SARS-CoV-2 exhibits ongoing mutations affecting disease presentation.
• Immune responses, including innate immunity and neutrophil extracellular traps, are significantly altered by infection.
• Vaccines vary in their ability to elicit specific immune responses.
• Therapeutic strategies show promise in managing COVID-19.

Conclusions:

• Continued research into SARS-CoV-2 immunity and evolving variants is essential.
• Advanced vaccines, effective medications, and robust public health measures are key to pandemic control.
• Emerging technologies will likely enhance future pandemic response strategies.
