Study Description

Brief Summary:

The purpose of this study is to investigate the safety of five consecutive lots of FSME-IMMUN NEW in healthy volunteers. The main criterion for investigation is the fever rate after the first vaccination in three different age classes. The immunogenicity of 0.25 ml FSME-IMMUN NEW has been demonstrated in previous clinical studies in children; therefore, in the present study, immunogenicity was investigated in a subgroup only.

Condition or disease	Intervention/treatment	Phase

Arms and Interventions

Outcome Measures

Eligibility Criteria

• Ages Eligible for Study: 1 Year to 15 Years (Child)
• Sexes Eligible for Study: All

Criteria

Inclusion Criteria:

Male and female children and adolescents will be eligible for participation in this study if:

• they are aged 1 year (from the 1st birthday) to < 16 years (to the last day before the 16th birthday);
• they are clinically healthy, (i. e. the physician would have no reservations vaccinating with FSME-IMMUN NEW outside the scope of a clinical trial);
• their parents/legal guardians understand the nature of the study and agree to its provisions;
• written informed consent is available from both parents/legal guardians,
• for Germany/Austria: additional written informed consent is available for children older than 8 years
• they or their parents/legal guardians agree to keep a volunteer diary.

For safety reasons, female volunteers who have reached sexual maturity at study start have to meet the following additional inclusion criteria:

- negative pregnancy test at study entry;

Exclusion Criteria:

Children and adolescents will be excluded from participation in this study if they:

• have a history of any TBE vaccination;
• have a history of TBE infection;
• have a history of allergic reactions to one of the components of the vaccine;
• suffer from a disease (e.g. autoimmune disease) or are undergoing a form of treatment (e.g. systemic corticosteroids, chemotherapeutics) that can be expected to influence immunological functions;
• are known to be HIV positive (a special HIV test is not required for the purpose of the study);
• have received banked blood or immunoglobulins within one month of study entry;
• have a history of vaccination against yellow fever and/or Japanese B-encephalitis;
• suffer from hemorrhagic diathesis;
• are participating simultaneously in another clinical trial;
• if female: are pregnant or breastfeeding.

Volunteers who meet the inclusion/exclusion criteria, but have a febrile illness (body temperature > 38°C) at the scheduled time of vaccination, will not be vaccinated before their body temperature returns to normal.

Volunteers who have received any other vaccination within 4 weeks prior to visit 1 will not be vaccinated until an interval of 4 weeks has passed. In this case visit 1 will take place separately.

If volunteers have received antipyretics within 4 hours prior to the intended TBE vaccination, the vaccination should be performed at a later time.

Volunteers who have a positive TBE antibody value prior to the first vaccination will be excluded from the statistical analysis of the primary endpoint.
