Post-vaccination SARS-CoV-2 antibody kinetics and protection duration against Omicron in elderly population

Résumé

Coronavirus disease 2019 (COVID-19) caused by the SARS-CoV-2 is particularly severe in older individuals because of an impaired immune response.1 The vaccines presently available are less efficacious in older individuals, because of the senescence of their immune systems.2 A recent letter in Journal of Infection showed the need of a third vaccine dose due to a waning antibody response against new SARS-CoV-2 variants in healthy and immunocompromised individuals.3 In this study, we analysed the protection against Omicron provided by the immune responses of nursing home residents (NHRs) and a population of healthcare workers (HCWs).
