3.2. Proliferative responses to H1N1 and to H3N2
The lower level of proliferative response to H1N1 was SI = 9 in
vaccinated healthy individuals used as controls. SIP 9 was therefore used to denote a positive response in patients.
Four recipients were tested before vaccination. Proliferative responses to H1N1 were at background, in all four as expected from
prior myeloablative conditioning (median SI = 1.5; range: 1–4).
