program (NIP) for their age group.
7. Male and female subjects of childbearing potential and at risk for pregnancy must

5. A previous anaphylactic reaction to any vaccine or vaccine-related component.
6. Bleeding diathesis or condition associated with prolonged bleeding time that would
contraindicate intramuscular injection.
7. A known or suspected defect of the immune system that would prevent an immune response

who are currently pregnant, or male and female subjects of childbearing potential who
are unwilling or unable to use a highly effective method of contraception as outlined
in this protocol for the duration of the study.
