The overall aim of this project is to evaluate the immunogenicity of TIV vaccination in HIV-infected non-pregnant women in 2013. Safety data including solicited local and systemic reactions to the vaccine will also be assessed.

Inclusion criteria
(i) Documented to be HIV-1 infected on one assay used in the Prevention of Mother to Child Transmission (PMTCT)/ other program undertaken within 12 weeks of study enrolment.
Exclusion criteria
WHO recommendation for influenza vaccines for 2013 for the Southern-hemisphere included the following vaccine strains:
Other names: Vaxigrip
Time frame: one month post vaccination
Humoral immunity will be measured by hemagglutination inhibition (HAI) assay, which has been extensively used for this purpose. In healthy individuals, HAI titers ≥1:10 indicate presence of influenza-specific antibodies and ≥1:40 protection against infection and disease. In this study we will use the following definitions to assess the humoral immune response to TIV: HAI titers <1:10 = seronegative; HAI titers ≥1:10 = seropositive; HAI titers ≥1:40 = sero-protective titers; and sero-conversion will be defined as HAI titers from <1:10 to ≥1:40 or ≥4-fold increase if pre-vaccination titers were ≥1:10.
Time frame: one month post vaccination
T-lymphocyte activation assays will be performed using state-of-the art polychromatic flow cytometry. The T- and B-cell phenotypes are assessed by flow cytometry using freshly thawed Peripheral Blood Mononuclear Cells (PBMC). Cells are stained using monoclonal antibodies against the comparator molecules.
Time frame: one month post vaccination
Interferon(IFN)Enzyme Linked Immuno Spot (ELISPOT) responses will be used to assess CMI responses to influenza vaccines.PBMCs will be separated and stimulated with influenza virus corresponding to the vaccine strains. Spots will be visualized with a ELISPOT plate reader. Results will be reported as Spot Forming Cells(SFC)/106 PBMCs.
Time frame: 1 week and one month post vaccination
Participants will remain in the clinic for at least 30 minutes after vaccination so that clinic personnel can observe participants for any potential adverse reactions.Report of vaccine-related local (redness, swelling, tenderness, itching,) and systemic (fever, malaise, myalgia, nausea, headache, rash) adverse events will be solicited at day 7 and day 28.
Time frame: within one month post vaccination
Safety and tolerability of the study vaccine will be monitored by means of Adverse Events (AEs) and toxicity reports presenting laboratory and clinical data.Toxicities will be classified by the Division of AIDS Table for Grading the Severity of Adult and Pediatric Adverse Events,
