Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Humoral immune response will be determined by the Haemagluttination inhibition test and respose is defined by the achievement of titres >40, which are considered protective. Enzyme linked ImmunoSPOT (ELIspot) will also quantify influenza specific B cell response. the cellular immune response will be measured by Intracellular Cytokine (i.e. IFN*, IL-2 and TNFa) detection by Flow Cytometry and assessment of proliferation of CD4 and CD8 T cells by Flow Cytometry. these parameters in patients will be compared to healthy controls | — |
