Immunogenicity and safety of live vaccines under immunosuppression

The study's primary objectives are the

1. Comparison of viremia levels after yellow fever vaccination in travelers under low dose methotrexate therapy (≤20mg/ /week) and healthy travelers at short intervals after vaccination
2. Comparison of yellow fever specific antibody levels after yellow fever vaccination in travelers under low dose methotrexate therapy (≤20mg/week) and healthy travelers at short intervals after vaccination

Secondary objectives

1. Comparison of the percentage of individuals who develop quantitative antibody levels >0.7 LNI (>0.5 IU/ml) in both groups at short intervals after vaccination
2. Safety assessment of yellow fever vaccination in both groups by studying adverse vaccine reactions
