Frequently asked questions about Fluarix

What is Fluarix used for?

Fluarix is an investigational vaccine being studied for the prevention of influenza and acellular pertussis. It is developed by GSK plc (GSK) and is currently in Phase 3 clinical development. Fluarix is being evaluated in controlled clinical trials for its immunogenicity and safety in adult populations.

Who makes Fluarix?

Fluarix is developed by GSK plc, a biopharma company traded under the ticker GSK. The vaccine is currently in Phase 3 clinical development for influenza and acellular pertussis indications. GSK has conducted multiple clinical trials to evaluate the vaccine's safety and immunogenicity.

What phase is Fluarix in?

Fluarix is in Phase 3 clinical development. It is an investigational vaccine being studied for influenza and acellular pertussis. As of the latest data, Fluarix is not approved and remains under clinical investigation. GSK plc is the developer of this vaccine candidate.

What clinical trials is Fluarix in?

Fluarix has been studied in 22 completed clinical trials with a total enrollment of 18,517 participants. Key trials include NCT00385255, a Phase 3 study evaluating coadministration with Boostrix in adults, and NCT00377585, a Phase 2 study of adjuvanted influenza vaccine. All trials are completed.

Is Fluarix the same as Boostrix?

No, Fluarix is not the same as Boostrix. Fluarix is an influenza vaccine, while Boostrix is a Tdap vaccine for tetanus, diphtheria, and acellular pertussis. They are separate vaccines developed by GSK, and a clinical trial (NCT00385255) studied their coadministration in adults.
