About this study

Official title: Adjuvanted Influenza Vaccination and Morbidity and Mortality in U.S. Nursing Homes

This study is powered to prospectively evaluate the relative effectiveness of adjuvanted trivalent influenza vaccine (aTIV; FLUAD) in preventing influenza mortality, hospitalization, and functional decline in a nursing home population in the U.S., compared to the commercially available, standard dose trivalent seasonal influenza vaccine (TIV; Fluvirin).

Read the detailed description

SUMMARY: A random study sample of up to 1000 NHs within 75 miles of the local area of the 121 cities where the CDC performs weekly influenza surveillance (estimated N= 11,239) may be offered the opportunity for participation; the first 1000 eligible to participate and accepting the offer will be enrolled. Participating facilities will be offered vaccine education for residents and staff, but will be randomly allocated to receive aTIV (FLUAD) vaccine or usual care (TIV) vaccination for their residents.

BACKGROUND: Lower respiratory tract infection (LRI), including pneumonia, bronchitis, and tracheobronchitis, is the leading cause of infectious mortality and hospitalization in older adults , and nursing home (NH) residents. Pneumonia and infection often produce attenuated signs and symptoms in older adults, leading to delayed or even misdiagnosis for this population. Diagnosis is further compromised due to few and sporadic clinician visits with nursing home residents, and reduced access to radiology. LRI may or may not directly lead to hospitalization, but LRIs are associated with considerable other morbidity than can result in hospitalization, including exacerbation of underlying cardiopulmonary diseases. Hospitalization rates for NH residents vary considerably between facilities, but the majority of hospitalizations occur during the 12 weeks during which influenza peaks each year.

OBJECTIVES: The primary objective is to estimate the differences in hospitalization rates during influenza season experienced by long-stay nursing home residents, between facilities using adjuvanted trivalent vaccine vs. standard trivalent vaccine. The secondary objective is to estimate the differences in the likelihood of Activities of Daily Living (ADL) functional decline and mortality rates in the study nursing homes, and influenza outbreaks.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • adjuvanted trivalent influenza vaccineBiological

    Also called Fluad, aTIV

    Nursing home residents over 65 years are allocated to receive adjuvanted trivalent vaccine. Residents under 65 years are provided standard trivalent vaccine (TIV-Fluvirin).

  • trivalent influenza vaccineBiological

    Also called Fluvirin, TIV

    Nursing home residents are allocated to receive standard trivalent vaccine (TIV).

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Hospitalization for a respiratory-related Illness (time frame: up to 1 year). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02882100, which also lists 6 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Mar 2023.
