Influenza Vaccine in HIV
A Controlled Trial to Assess the Immunogenicity and Efficacy of Three Vaccine Dosing Strategies in HIV Infected Adults
The purposes of this research study are:
- to see if there is a difference in the quantity of protective influenza antibodies produced by different doses of the Fluviral vaccine
- to see if these different vaccine dosing schedules reduce flu-like illness and/or reduce laboratory documented influenza in HIV Infected adults.
Studieoversigt
Detaljeret beskrivelse
Immune compromised individuals are at risk for infection with influenza and more likely to manifest more severe symptoms of influenza disease. Furthermore, they are influenza vaccine hyporesponsive in comparison to healthy, adult immune competent individuals. One population of immune compromised Canadians at risk for severe influenza disease is those living with HIV infection. At least 56,000 Canadians are HIV infected [1]. This population is at risk for more severe influenza illness. Influenza viral replication and shedding is prolonged and the duration of influenza symptomatology is longer in those with HIV [2, 3]. Furthermore, influenza-related mortality rates in HIV infected individuals are increased [4]. The HIV population is known to be hyporesponsive to vaccinations, including influenza. The efficacy of influenza vaccines is compromised, in part, by reduced antibody responses observed in HIV infected individuals [5]. Nevertheless, influenza vaccination is recommended for HIV-infected individuals [6, 7]. The Centers of Disease Control guidelines state: "Influenza can result in serious illness and because vaccination with inactivated influenza vaccine might result in the production of protective antibody titers, vaccination might benefit HIV-infected persons. Therefore, influenza vaccination is recommended". As influenza vaccination is the cornerstone of public health interventions intended to protect the population against influenza, vaccine hyporesponsiveness in immune compromised populations represents a significant concern. Given the risk of influenza exposure in general as well as concerns related to poor vaccine efficacy and more severe influenza disease in immune compromised populations such as those living with HIV, strategies to improve vaccine efficacy are required.
Therefore a total of 5 conditions provide justification for a trial to be conducted at this time:
- current standard treatment with influenza vaccine is less efficacious when used in particular subgroups of immune compromised individuals, such as those diagnosed with HIV
- there exists a significant burden of influenza infection in HIV patients that must be addressed in terms of identifying an effective treatment strategy
- past randomized trials of influenza vaccination in HIV patients are of limited comparability to today's relevant base of patients, and alternative vaccination strategies require assessment
- efficacy of booster doses of influenza vaccine in HIV patients remains in question as a consequence of methodologic shortcomings in terms of both design aspects and outcomes measured of past studies
- there is a paucity of published evidence assessing the efficacy of an increased, double-dose of influenza vaccine in this patient population.
