| Primary | Quantification of NK Cells (CD3-/CD56+). | Investigators will collect a 6mL blood sample into EDTA anti-coagulant tubes before and during the last five minutes of an albuterol nebulization to assess the quantification in both absolute number and proportion of NK cells (CD3-/CD56+) using a MACSQuant flow cytometer and subsequent analysis on FlowLogic Software (v7.2.1). The last five minutes of nebulization of blood sample will be directly compared to the pre nebulization blood sample in the same participants in the same research arm. | One year | |
| Primary | Quantification of Gamma Delta T Cells (CD4-CD8-). | Investigators will collect a 6mL blood sample into EDTA anti-coagulant tubes before and during the last five minutes of an albuterol nebulization to assess the quantification in both absolute number and proportion of Gamma Delta T cells (CD3+/CD4-/CD8-) using a MACSQuant flow cytometer and subsequent analysis on FlowLogic Software (v7.2.1). The last five minutes of nebulization of blood sample will be directly compared to the pre nebulization blood sample in the same participants in the same research arm. | One year | |
