Abstract:
The human response to vaccination exhibits considerable variability due to a complex interplay of heritable and environmental factors. This review examines the current understanding of the role of human genetics in vaccine responses, encompassing both rare adverse events following immunization as well as immunogenicity and efficacy. We highlight recent studies including from the coronavirus disease 2019 (COVID-19) pandemic, which provided a unique opportunity to study vaccine genetics at scale for a newly emerging infection and revealed significant associations between HLA alleles and responses to SARS-CoV-2 vaccines. Understanding genetic contributions to vaccine responses holds promise for enhancing vaccine safety and efficacy, and the development of personalized vaccination strategies.

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
