Tetravalent influenza vaccine(Abbott)

Sleep is an important modulator of the immune response, whereby sleep disturbances (ie, poor sleep quality, insufficient sleep and/or primary sleep disorder, obstructive sleep apnea (OSA)) contribute to inflammatory disease risk and dysregulation of immune response in front of infectious agents.
The objective of this study is to evaluate the impact of undiagnosed and non-treated sleep disorders on innate immunity in a cohort of COVID-19 patients and the role of trained immunity induced by influenza vaccination in the innate immune response.
