  • New occurrence or new awareness of Guillain-Barré Syndrome since receipt of Dose 1.
  • Any unresolved or continuing solicited or unsolicited Grade 2 or greater severity adverse events, including reactogenicity events, that have occurred since receipt of Dose 1 without a clear, alternative etiology. Unresolved or continuing Grade 1 adverse events are permissible unless, in the opinion of the site principal investigator or appropriate sub-investigator, they would render vaccination unsafe, would interfere with the evaluation of responses or are not generally seen in "normal, healthy subjects".
  • Grade 2 or greater severity clinical safety lab values (according to the toxicity table, Section 11.1.1.2) that do not return to Grade 1 or less prior to the second vaccination. If the clinical safety lab values return to Grade 1 or less, vaccination should be rescheduled within the acceptable window for the second vaccination - see Section 10.3.3. Subjects who experienced a Grade 3 or above clinical safety laboratory adverse event since receipt of Dose 1 should be excluded from receipt of second vaccination. Subjects who had a Grade 3 or above clinical safety laboratory adverse event prior to first vaccination will be evaluated by the site principal investigator and DMID Medical Monitor to determine receipt of second vaccination.
  • Have an acute illness, including an oral temperature greater than or equal to 100.4 degrees F, within 3 days prior to the second vaccination. Vaccination of subjects should be deferred until acute illness, including an oral temperature greater than or equal to 100.4 degrees F, has resolved. If resolution occurs, vaccination should be rescheduled within the acceptable window for the second vaccination - see Section 10.3.3.
  • Emergence of Grade 2 or greater severity signs or symptoms since receipt of Dose 1 that could confound or confuse assessment of vaccine reactogenicity.
  • Any new clinical findings since receipt of Dose 1, which in the opinion of the site principal investigator or appropriate sub-investigator, would compromise the safety of the subject or would interfere with the evaluation of responses or successful completion of the study.
  • Plan to travel outside the U.S. in the time between the second vaccination and 21 days following the second vaccination.
  • Subject refuses further vaccination. Subjects who do not receive the second vaccination will be asked to return for safety assessments and for scheduled venous blood sample collections for clinical safety laboratory and immunogenicity evaluations and will be followed for the duration of the study - see the protocol-specific Manual of Procedures (MOP) for further details.
  • Subject withdraws consent. The subject may withdraw their consent for study participation at any time and for any reason, without penalty.
