Inclusion Criteria: - Subjects who the investigator believes can and will comply with the requirements of the protocol. - Written informed consent obtained from the subject. - Male and female adults, >= 18 years of age at the time of the first vaccination. - Satisfactory baseline medical assessment by history and physical examination. - Safety laboratory test results within the parameters specified in the protocol. - Comprehension of the study requirements, ability to comprehend and comply with procedures for collection of safety data, expressed availability for the required study period, and ability and willingness to attend scheduled visits as demonstrated by signature on the informed consent document. - Access to a consistent means of telephone contact, which may be either in the home or at the workplace, land line, or mobile, but NOT a pay phone or other multiple-user device. - Female subjects of non-childbearing potential may be enrolled in the study. - Female subjects of childbearing potential may be enrolled in the study, if the subject: - has practiced adequate contraception for 30 days prior to vaccination; and - has a negative pregnancy test on the day of first vaccination; and - has agreed to continue adequate contraception during the entire treatment period and for 2 months after completion of the vaccination series. Exclusion Criteria: - Medical history of physician-confirmed infection with an A/California/7/2009 (H1N1)v-like virus. - Previous vaccination at any time with an A/California/7/2009 (H1N1)v-like virus vaccine. - With the exception of seasonal influenza vaccination, administration of any vaccine(s) within 30 days before study vaccination on Day 0.
