Study Details

Study Description

Brief Summary

A total of 18,000 eligible subjects (or 6,000 subject distributed evenly between the 3 study arms) will be enrolled. Eligible subjects will be randomized in 1:1:1 (cell-culture-based vaccine, the recombinant vaccine, or the egg-based vaccine) over four influenza seasons (2018-2019, 2019-2020, 2020-2021, and 2021-2022).

Condition or Disease Intervention/Treatment Phase
  • Biological: Egg based influenza vaccines
  • Biological: Recombinant influenza vaccines
  • Biological: Cell-culture based influenza vaccines
Phase 4

Detailed Description

This four-year, pragmatic, prospective study will compare the effectiveness of licensed egg-based inactivated influenza vaccines to the effectiveness of two other types of licensed vaccines, the cell-culture based inactivated influenza vaccine and the recombinant influenza vaccine, in the prevention of laboratory-confirmed influenza infection in active duty members, military retirees, and other DoD beneficiaries. Military treatment facilities (MTFs) in the United States will participate in this protocol. Enrollment will be restricted to adults (≥18 years and older) who are preparing to receive seasonal influenza vaccination at participating DoD sites. Subjects will be randomized to receive one of the three licensed influenza vaccines types for evaluation of effectiveness. There is no exclusion for pregnancy, as none of these licensed products are contraindicated in pregnant women.

Arms and Interventions

Arm Intervention/Treatment
Active Comparator: Egg based influenza vaccines

Quadrivalent egg-based vaccines, which contain an inactivated form of the virus. Vaccines will be given to the participant in accordance with standard clinical practices for those in the US military. All egg-based vaccines are FDA licensed for use in the United States.

Biological: Egg based influenza vaccines
Participants will be randomly allocated to one of three vaccine types in accordance with standard clinical practices for those in the US military. All vaccines are FDA licensed for use in the United States.

Active Comparator: Recombinant influenza vaccines

FluBlok, recombinant HA influenza vaccine. Vaccines will be given to the participant in accordance with standard clinical practices for those in the US military. Flublok Quadrivalent is a quadrivalent recombinant influenza vaccine that has been licensed by the FDA for use in the United States.

Biological: Recombinant influenza vaccines
Participants will be randomly allocated to one of three vaccine types in accordance with standard clinical practices for those in the US military. All vaccines are FDA licensed for use in the United States.

Active Comparator: Cell-culture based influenza vaccines

Flucelvax, Madin-Darby canine kidney (MDCK)-cell-culture based inactivated influenza vaccine. Vaccines will be given to the participant in accordance with standard clinical practices for those in the US military. Flucelvax quadrivalent, the only cell-based flu vaccine FDA licensed for use in the United States.

Biological: Cell-culture based influenza vaccines
Participants will be randomly allocated to one of three vaccine types in accordance with standard clinical practices for those in the US military. All vaccines are FDA licensed for use in the United States.

Outcome Measures

Primary Outcome Measures

  1. Laboratory confirmed influenza attack rates [Onset > 13 days after vaccination up to 1 year]

    Laboratory-confirmed influenza as ascertained by a sensitive and specific assay is needed to assess effectiveness.

Secondary Outcome Measures

  1. Hemagglutination Inhibition (HI) titer responses to vaccine and circulating strains of influenza [Baseline to 21-35 days post vaccine]

    A subset of volunteers may participate it in this outcome.

  2. Pseudovirion neutralization (PVN) responses to vaccine and circulating strains of influenza [Baseline to 21-35 days post vaccine]

    A subset of volunteers may participate it in this outcome.

  3. Anti-Neuraminidase (Anti-NA) titer responses to vaccine and circulating strains of influenza [Baseline to 21-35 days post vaccine]

    A subset of volunteers may participate it in this outcome.

  4. Cellular Responses: Frequency of antigen specific CD4 and CD8 cells, B cells [Baseline to 21-35 days post vaccine]

    A subset of volunteers may participate it in this outcome.

  5. Rate of Influenza-like Illness [Onset > 13 days after vaccination up to 1 year]

  6. Frequency of influenza confirmed hospitalization [Onset > 13 days after vaccination up to 1 year]

  7. Number of duty (work) days lost due to Influenza-like Illness [Onset > 13 days after vaccination up to 1 year]

Other Outcome Measures

  1. Tertiary Arm- Assess the burden of covid-19 and explore the inter-relationship between influenza and covid-19 [onset >13 days after vaccination]

    Endpoints: incidence of COVID-19 incidence of co-infection with influenza & Severity of COVID-19, symptoms associated with COVID-19 infection (compared with influenza, other respiratory viruses)
