Subjects were asked whether they had received previous influenza vaccinations and whether it was within 2 years or more from joining the trial.

previous influenza vaccination

Serum samples were collected at screening (summer-autumn 2016) and later analysed for pre-existing neutralising antibodies against the main influenza strains that circulated in the Netherlands during the influenza season of 2016-2017 (B/Phuket/3073/2013, B/Brisbane/60/2008, A/Hong Kong/5738/2014 (H3N2) and A/Michigan/45/15 (H1N1)). The number of subjects with a HA titer for A strains ≥ 40 and with HA ≥ 80 for B strains was recorded in each group.

HAI titer at screening

To compare the number of subjects that showed at least a two-fold increase on day 42 and day 180 following vaccination in the number of CD4+T-cells secreting TH1 cytokines in all groups.

Percentage of CD4+ TH1 Cytokine Responders

Responders were defined as subjects having at least a two-fold increase in the amount of IFNg secreted on day 42 and day 180 compared the amount secreted on day 0. IFNg was measured by ELISA

Percentage of Responders on Day 42 and Day 180 for IFNgamma Secretion by PBMCs

To evaluate the solicited AEs in all subjects

Solicited AEs

To evaluate the level of TH2 cytokines (IL-4) from baseline in all groups 42 and 180 days following FLU-v vaccination.

Th2 Cytokine Responses (IL-4)

To evaluate the humoral immune responses specific to FLU-v from baseline in all groups 42 and 180 days following FLU-v vaccination. Specific FLU-v IgG antibodies were measured by ELISA. The geometric mean for each treatment group was provided.

Antibody Responses to FLU-v

To evaluate unsolicited AEs and SAEs in all subjects

Unsolicited AEs and SAEs

To evaluate the change from baseline in cellular immune responses based on additional CMI assays such as ELISPOT (Enzyme-Linked ImmunoSpot) in all groups at 42 and 180 days following FLU-v vaccination

Immune Responses Measured by IFNgamma/Granzyme B ELISPOT

During the influenza season (Dec 2016 to March 2017), fully vaccinated subjects will contact the trial center immediately if they feel unwell for 24h, with a sudden onset of flu-like symptoms. The medical staff will arrange for a nasopharyngeal swab to be performed if the subject has at least one respiratory (cough, sore throat, shortness of breath, runny nose, stuffy nose, sneezing and earache) and one systemic symptom (fever, malaise, headache and myalgia (muscle and joint pain). Swabs should be taken from the reported subjects within 3 days from the trial center being contacted or within 4 days of the onset of symptoms, whatever time is shorter.

Percentage of Participants Who Tested Positive for Influenza Strains

Subjects recorded daily influenza symptoms from December 2016 up to March 2017. Subjects with a sudden onset of at least one respiratory and one systemic symptom were swabbed. If the results were positive for influenza then the symptoms were included in the analysis. The duration of symptoms was recorded as the number of symptomatic days during the influenza episode. Fever (≥38oC), malaise, headache, myalgia (muscle and joint pain), cough, sore throat, shortness of breath, runny nose, stuffy nose, sneezing and earache were scored on a severity scale of 0 to 3 (0: no symptom, 1: mild, 2: moderate, 3: severe). The daily severity score was the sum of the severity score for all symptoms listed above on a single day. The total score was the sum of all daily scores during the influenza episode. The peak score was the highest daily score during the influenza episode. The average score was the total score divided by the number of days the influenza episode lasted.

Severity of Symptoms in RT-PCR Influenza-confirmed Subjects.

Subjects recorded daily influenza symptoms from December 2016 up to March 2017. Subjects with a sudden onset of at least one respiratory and one systemic symptom were swabbed. If the results were positive for influenza then the symptoms were included in the analysis. The duration of symptoms was recorded as the number of symptomatic days during the influenza episode. The following symptoms were recorded: fever (≥38oC), malaise, headache, myalgia (muscle and joint pain), cough, sore throat, shortness of breath, runny nose, stuffy nose, sneezing and earache.
