parent(s)/LAR(s) (participant must be able to understand the informed consent) prior
to performance of any study-specific procedure.

Written informed assent obtained from the participant (participant must be able to
understand the informed assent) if he/she is less than the legal age prior to performance
of any study-specific procedure.

Specific inclusion criteria for all participants in Cohort 1 • A male or female participant
18-49 YOA at the time of the study intervention administration.

- Participants should be diagnosed with at least 1 of the following medical conditions
if considered medically stable by the investigator:

Key exclusion criteria
Medical conditions

- Any confirmed or suspected immunosuppressive or immunodeficient condition resulting

attend study site visits). Study participants may decide to assign a caregiver to help
them complete the study procedures.

- Significant underlying illness that in the opinion of the investigator would be
expected to prevent completion of the study (e.g., life-threatening disease).

- Any medical condition that in the judgment of the investigator would make
intramuscular injection unsafe.

- Any other clinical condition that, in the opinion of the investigator, might pose
additional risk to the participant due to participation in the study.

Prior/Concomitant therapy

- Use of any investigational or non-registered product (drug, vaccine, or medical
device) other than the study intervention during the period beginning 30 days before
the dose of study intervention (Day -29 to Day 1), or planned use during the study
period (up to Visit 3, Month 6).

- Planned or actual administration of a vaccine not foreseen by the study protocol in
the period starting 30 days before and ending 30 days after the dose of study
intervention administration, with the exception of inactivated, subunit and split
influenza vaccines or COVID-19 vaccines which can be administered up to 14 days before
or from 14 days after the study intervention administration.

- Previous vaccination with any RSV vaccine, including investigational RSV vaccines.

- Chronic administration of immune-modifying drugs (defined as more than 14 consecutive
days in total) and/or administration of long-acting immune-modifying treatments or
planned administration at any time up to the End-of-study (EOS).

- Up to 3 months prior to the study intervention administration:

- For corticosteroids, this will mean prednisone >=20 mg/day, or equivalent.
Inhaled, topical and intra-articular steroids are allowed

- Administration of immunoglobulins and/or any blood products or plasma
derivatives

- Up to 6 months prior to study intervention administration: long-acting
immune-modifying drugs including among others immunotherapy (e.g., Tumor Necrosis
Factor (TNF)-inhibitors), monoclonal antibodies, antitumoral medication.

Prior/Concurrent clinical study experience

• Concurrently participating in another clinical study, at any time during the study
period, in which the participant has been or will be exposed to an investigational or a
non-investigational vaccine/product (drug or invasive medical device).

Other exclusions:

Other exclusions for all participants

- History of chronic alcohol consumption and/or drug abuse as deemed by the investigator
to render the potential participant unable/unlikely to provide accurate safety reports
or comply with study procedures.

- Bedridden participants.

- Planned move during the study period that will prohibit participating in the study
until study end.

- Participation of any study personnel or their immediate dependents, family, or
household members.
