Assessing T cell immunity is crucial for developing COVID-19 countermeasures. This review details common methods for measuring cell-mediated immunity, highlighting their benefits and limitations for SARS-CoV-2 research.
Area of Science:
- Immunology
- Virology
- Vaccinology
Background:
- Effective immunosurveillance is vital for developing therapeutics, vaccines, and containment strategies against novel pathogens like SARS-CoV-2.
- The COVID-19 pandemic underscored the urgent need for rapid assessment of immune memory post-infection or vaccination.
- Standardization of cellular assays for measuring cell-mediated immunity remains a challenge across studies.
Conclusions:
- A combination of immunological assessment approaches may be optimal for comprehensive T cell immunity evaluation.
- Standardization efforts are needed to improve the reliability and comparability of T cell assays in infectious disease research.
- Understanding the strengths and weaknesses of each assay is critical for accurate interpretation of immune responses to SARS-CoV-2.
