6-month-old children

In overall good health, without any clinically significant concomitant disease states (e.g., renal failure, hepatic dysfunction, cardiovascular disease, etc.) and no clinically significant abnormal finding on history and/or physical examination

Fully immunised for age according to the Swiss vaccination schedule

Disqualifiers

Contra-indications to MMR, including

immunosuppression (i.e. proven, suspected, or planned)

Trial outcomes

Primary outcomes

1

Incidence of respiratory infection within the 3 months following randomisation

Incidence of parent-reported respiratory infections between 6 months and 9 months of age using fortnightly REDCap questionnaires, with validation of data by confirmation with treating paediatrician and medical records.

Time frame
Measured over the 3 months following randomisation

Secondary outcomes

1

Infection: Time to first infection within the 3 months following randomisation

Calculated as: For participants who have an event: Date of event onset - date of randomisation For participants who did not have an event: Earliest censoring date - date of randomisation

Time frame
Measured over the 3 months following randomisation
2

Infection: Time to first infection within the 18 months following randomisation

Calculated as: For participants who have an event: Date of event onset - date of randomisation For participants who did not have an event: Earliest censoring date - date of randomisation

Time frame
Measured over the 18 months following randomisation
3

Infection: Prevalence of infection within the 3 months following randomisation

Calculated as: number of participants who have an event / total number of participants

Time frame
Measured over the 3 months following randomisation
4

Infection: Prevalence of infection within the 18 months following randomisation

Calculated as: number of participants who have an event / total number of participants

Time frame
Measured over the 18 months following randomisation

Other outcomes

1

Allergic/atopic diseases: time to first allergic/atopic disease flare within the 3 months following randomisation

Calculated as: For participants who have a flare: Date of event onset - date of randomisation For participants who did not have a flare: Earliest censoring date - date of randomisation

Time frame
Measured over the 3 months following randomisation
2

Allergic/atopic diseases: time to first allergic/atopic disease flare within the 18 months following randomisation

Calculated as: For participants who have a flare: Date of event onset - date of randomisation For participants who did not have a flare: Earliest censoring date - date of randomisation

Time frame
Measured over the 18 months following randomisation
3

Allergic/atopic diseases: Prevalence of allergic/atopic disease within the 3 months following randomisation

Calculated as: number of participants who have a flare / total number of participants

Time frame
Measured over the 3 months following randomisation
4

Allergic/atopic diseases: Prevalence of allergic/atopic disease within the 18 months following randomisation
