Female subject is pregnant (or has a positive pregnancy test prior to vaccination) or breast feeding, or planning to become pregnant within 3 months after the last boost vaccination.~4. Fever (\> / = 38.0 Degrees Celsius / 100.4 Degrees Fahrenheit) or other acute illness within 3 days prior to first vaccination.~5. Infection requiring systemic antibiotics or antiviral treatment within the 7 days prior to first vaccination.~6. Has a positive urine drug screen for amphetamines\*, cocaine, opiates, or phencyclidine.~   \*Prescription amphetamines are not exclusionary.~7. Chronic, clinically significant medical or psychiatric conditions\* that, in the opinion of the investigator, may pose additional risk to the subject if she/he participates in the study.~   \*Permissible conditions include but are not limited to mild, well-controlled asthma, well-controlled depression, well-controlled anxiety, seasonal allergies, and well-controlled hypertension.~8. Receipt of immunosuppressive drugs\*,\*\*,\*\*\* or biologic agents within the 30 days prior to enrollment.~   \*This includes use of oral or parental prednisone.

The use of low or moderate dose inhaled steroids is permissible. Doses are defined as per age as using inhaled high-dose per reference chart in the National Heart, Lung and Blood Institute Guidelines for the Diagnosis and Management of Asthma (EPR-3) or other lists published in UPTODATE.~   \*\*Receipt of systemic, prescription medications for the treatment of chronic medical conditions or variations of normal physiologic functions may be permissible if, in the opinion of the investigator, they are used for conditions that are not clinically significant and would not impact the safety of the subject or the safety and immunogenicity outcomes of the protocol.~   \*\*\*Use of systemic, over-the-counter medications and PRN systemic, prescription medication may be allowed if, in the opinion of the investigator, they pose no additional risk to subject safety or assessment of immunogenicity/reactogenicity.~9. Has known neoplastic disease\* anticancer therapy, or radiation therapy within 3 years prior to first study vaccination.~   \*Excluding non-melanoma skin cancer, such as squamous cell skin cancer or basal cell skin cancer, cured by surgical excision.~10.
