Brief summary

The purpose of this study is to evaluate the immunogenicity, safety, and reactogenicity of the RSVPreF3 OA investigational vaccine in an immunocompromised (lung and renal transplant recipients) population and assess whether a second dose of the vaccine increases the immune response.

Interventions

0.5 mililiter dose was administered intramuscularly as 1 dose to RSV\_IC\_1 and RSV\_HA groups, and 2 doses to RSV\_IC\_2 group.

The CMI is measured in a subgroup consisting of participants with renal and lung SOT (from RSV\_IC\_1 and RSV\_IC\_2 groups) and healthy participants (from RSV\_HA group).

Time frame: At pre-study intervention administration (at Visit 1 [Day 1]), Visit 2 (Visit 1 + 7-14 days), Visit 3 (Visit 1 + 30-60 days) and Visit 4 (Visit 3 + 30-42 days)

Population: Analysis was performed on PPS for CMI. Only participants with data available for CD8+ T cells for the specified groups at the specified timepoints were included in this analysis.

RSV-A Serum Neutralizing Titers Expressed As Group GMT For RSV_IC_1 And RSV_IC_2 Groups

Group GMT of RSV\_IC\_2 over RSV\_IC\_1 was assessed at Visit 4. The ANCOVA model used to calculate the adjusted GMTs for RSV-A neutralizing titers included the baseline log10-transformed titer and the SOT type as covariate (i.e. GMTs are adjusted for the PRE timepoint values) and only included RSV\_IC\_1 and RSV\_IC\_2 groups in the model as fixed effect, as specified in Statistical Analysis Plan.

Time frame: At Visit 4 (Visit 3 [Visit 1 (Day 1) + 30-60 days] + 30-42 days)

Population: Analysis was performed on PPS for humoral immunogenicity. Only participants with data available for the specified groups at the specified timepoints were included in this analysis.
