Bioinformatic Tools for Studying the Cellular Immune Response to SARS-CoV-2, Vaccine Efficacy, and Future Pandemics at the Global Population Level. Int J Mol Sci. 2024 Dec 16;25(24):13477.https://hdl.handle.net/20.500.12105/26576Antigen recognition by human leukocyte antigen (HLA) restriction is critical for an adequate antiviral response in both natural infection and vaccination. However, the overwhelming polymorphism of HLA, with nearly 40,000 alleles identified, is an important limitation for the global analysis of cellular immune responses and vaccine efficacy. In this narrative review, we included several immunoinformatics studies performed in our laboratory to circumvent this limitation. These analyses focused on studying the cellular immune responses restricted by the most common HLA alleles, and their role in vaccine efficacy. Computational studies validated experimentally, such as our laboratory has carried out, represent a useful, rapid, and cost-effective strategy to combat future pandemics.engVoRhttp://creativecommons.org/licenses/by/4.0/HLASARS-CoVCellular responseImmunoinformaticsVaccineCOVID-19 VaccinesCOVID-19Computational BiologyHLA AntigensHumansImmunity, CellularPandemicsSARS-CoV-2Vaccine EfficacyAttribution 4.0 International3976924025241347710.3390/ijms2524134771422-0067International journal of molecular sciencesopen access
