Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.

Humoral immunogenicity
The plaque reduction neutralisation test (PRNT), which measures the serum dilution capable of preventing 50% of plaque formation induced by measles virus in cell cultures, has been considered the most reliable criterion for the serologic evaluation of measles immunity. For PNRT, the protective cutoff titer is defined to be \>120. A frequency of 95% seroconversion rate, i.e. children mounting a protective level of humoral immunity according to the abovementioned cutoff value after MMR-vaccination at 6 M of age will be considered sufficient to suggest implementation of MMR at 6 M in the Danish vaccination programme.
Time frame: 1 months after intervention
Hospitalisation for infection
Significant decrease in hospitalisation for infection measured as repeated events from 6 to 12 months of age in children randomised to MMR at 6 M compared to children randomised to placebo. Information about hospitalisation for infection will be obtained from the national Danish Patient Register, where all Danish inhabitants are followed-up during all hospital contacts.
Time frame: 6-12 months of age
