5. History of severe allergic reaction after previous vaccinations or hypersensitivity to any vaccine component;
6. Significant acute or chronic infection within the previous 7 days or body temperature higher or equal to 38C degrees within the previous day;
7. Antibiotics within 6 days prior to enrollment;
8. Any serious chronic or progressive disease according to the judgment of the investigator (e.g., neoplasm, insulin dependent diabetes mellitus Type I, cardiac disease, hepatic disease, progressive neurological disease or seizure, either associated with fever or as part of an underlying neurological disorder or syndrome, autoimmune disease, HIV infection or AIDS, or blood dyscrasias or diathesis, signs of cardiac or renal failure or severe malnutrition);

Furthermore, subjects must have received HepB vaccine preferably at 0, 1 month of age, with the second dose at least 14 days prior to study vaccination. Influenza vaccine should be administered at least 14 days before or 14 days after study vaccination; Rotavirus vaccine may be administered during the study as per local practice.
