What this study is testing
To demonstrate non-inferiority of humoral immune response to RSVPreF3 OA investigational vaccine when co-administered with a COVID 19 mRNA vaccine compared to RSVPreF3 OA investigational vaccine administered alone. To demonstrate non-inferiority of humoral immune response to a COVID-19 mRNA vaccine when co-administered with the RSVPreF3 OA investigational vaccine compared to COVID-19 mRNA vaccine administered alone.

Who can take part
You may be able to join if
- Participants, who, in the opinion of the investigator, can and will comply with the requirements of the protocol (e.g., completion of the diary cards, return for follow-up visits). INC#1

- A male/female of ≥50 YOA at the time of the first study intervention administration. INC#3
- Participants who are medically stable in the opinion of the investigator at the time of first vaccination. Participants with chronic stable medical conditions with or without specific treatment, such as diabetes, hypertension or cardiac disease, are allowed to participate in this study if considered by the investigator as medically stable. INC#4
- Participants living in the general community or in an assisted-living facility that provides minimal assistance, such that the participant is primarily responsible for self-care and activities of daily living. INC#5
- Participants who have received previously a SARS-CoV-2 vaccine, being administered at least 3 months prior to study vaccination. INC#6
You likely can't join if
- History of any reaction or hypersensitivity likely to be exacerbated by any component of the study interventions, including a known history of severe allergic reaction (e.g., anaphylaxis). EXC#1
- Any other clinical condition that, in the opinion of the investigator, might pose additional risk to the participant due to participation in the study. EXC#10
- Recent SARS-CoV-2 infection within 3 months prior to the COVID-19 vaccine dose administration. Timelines to be determined from symptoms onset or positive COVID-19 test (if infection was asymptomatic). EXC#11
- Use of any investigational or non-registered product (drug, vaccine or invasive medical device) other than the study interventions during the period beginning 30 days before the first dose of study interventions and ending 30 days after the last vaccine administration, or their planned use during the study period. EXC#12
- Planned administration of a vaccine in the period starting 30 days before the first dose and ending 30 days after the last dose of study intervention(s) administration*, with the exception of inactivated and subunit influenza vaccines which can be administered up to 14 days before or from 14 days after the study vaccination. EXC#13
- "• Chronic administration of immune-modifying drugs (defined as more than 14 consecutive days in total) and/or planned use of long-acting immune-modifying treatments at any time up to the last blood sampling visit. EXC#14 Up to 3 months prior to the study intervention administration: o For corticosteroids, this will mean prednisone equivalent ≥ 20 mg/day. Inhaled and topical steroids are allowed. o 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., TNF-inhibitors), monoclonal antibodies and antitumoral medication."
