Changes in antiretroviral dosage within 8 weeks prior to entering the study are permitted. In addition, the exchange of pharmacological formulation (eg. the conventional formulation for combination formulations) is allowed. If the volunteer is not on regular antiretroviral treatment, he/she should not have received any dose of any antiretroviral within 8 weeks prior to screening, including for the prevention of HIV vertical transmission (previous prophylactic and therapeutic regimens are allowed)~* Without planning to change or start HAART in the next 6 months.~Inclusion criteria - unique to the participants without HIV infection (control group):~* HIV-negative test result documented by rapid test approved in Brazil~* Health professionals with indication of receiving H1N1 virus vaccine~Exclusion Criteria:~* Use of any systemic anticancer or immunomodulator treatment, corticosteroid, experimental vaccines, interleukins, interferons, growth factors or intravenous immunoglobulin (IVIG) within 45 days prior to entry into the study.~* Pregnancy or lactation.~* Allergy and/or sensitivity or any known hypersensitivity to residues present in the vaccine (egg, chicken protein, egg albumin, formaldehyde, gentamicin sulphate and sodium deoxycholate) and/or thimerosal.~* Use of alcohol or addiction or other conditions which in the opinion of the site's investigator, may interfere with compliance to the study requirements.~D5. Serious illness requiring systemic treatment and/or hospitalization within 45 days prior to entry into the study~* Severe febrile illness or acute infection at the time of screening for the study and/or days of vaccination~* Vaccination against seasonal influenza in the last 12 months prior to study entry~* Previous vaccination against influenza A H1N1~* History or family history of Guillain-Barré Syndrome (parents, siblings, half-siblings or children).~* Diagnosis of neurological condition including (but not limited to) the absence of deep tendon reflexes, Achilles and patellar, in both legs (four missing) in the last six months.~* Disproportionate force loss in lower limb(s) compared to the upper limbs in the last six months.

Study Arms:
- 3.75 µg of the vaccine on days 0 and 21 (Type: EXPERIMENTAL): Patients infected with HIV will receive 3.75 µg of an adjuvanted A H1N1 vaccine in two applications 21 days apart.
- 7.5 µg of the vaccine on days 0 and 21 (Type: EXPERIMENTAL): Patients infected with HIV will receive 7.5µg of an adjuvanted A H1N1 vaccine in two applications 21 days apart.
- 3.75 µg of the vaccine on day 0 (Type: ACTIVE_COMPARATOR): The volunteers in the control group will receive a single application of 3.75 µg dose of the vaccine.

Based on this trial design, predict the completion outcome and termination type (if applicable).
