Inclusion and exclusion criteria
Inclusion criteria:
- 1. Participants and/or participants’ parents/LARs, who, in the opinion of the investigator, can and will comply with the requirements of the protocol (e.g., completion of the eDiary, return for follow-up visits). 2. Written or witnessed/thumb printed informed consent obtained from the participant/participant’s parent(s)/LAR(s) of the participant prior to performance of any study specific procedure. 3. Written or witnessed/thumb printed informed assent obtained from participants below the legal age of consent prior to performance of any study specific procedure. 4.

For corticosteroids, this will mean prednisone equivalent ≥20 mg/day for adult participants and ≥0.5 mg/kg/day with maximum ≥20 mg/day for pediatric participants. Inhaled and topical steroids are allowed. 15. 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 medical device). 16.
