Seqirus to Present Data on Pandemic and Seasonal Influenza Vaccines at OPTIONS X Conference

SUMMIT, N.J., Aug. 22, 2019 /PRNewswire/ -- Seqirus, a global leader in influenza prevention, today announced it will feature data in 3 presentations and 24 posters on the company’s adjuvant and cell-based vaccines for seasonal and pandemic influenza at the Options for the Control of Influenza (OPTIONS X) Conference in Singapore.

In particular, Seqirus will present clinical data on a seasonal adjuvanted influenza vaccine, including studies that assessed immune response against homologous and heterologous influenza strains and cross-reactive antibodies in young children (≥ 6 months old up to 6 years old).^1,2 The company will also feature studies on a pandemic adjuvanted, cell-based H5N1 vaccine that examined immune responses against heterologous A (H5N1) strains in young children (6 months to ≤ 17 years old), adults (18 to < 65 years) and elderly populations (65 years and older), as well as a retrospective analysis on the level of antigenic similarity of cell-based versus egg-based influenza vaccine reference strains and circulating influenza B viruses.^3,4,5

“As a company on the front line of influenza prevention, we are committed to developing innovative technologies, like adjuvanted and cell-based vaccines, to help improve influenza prevention,” said Russell Basser, MD, Chief Scientist and Senior Vice President of Research and Development at Seqirus. “We look forward to sharing our latest data at OPTIONS X and continuing to develop our broad portfolio of vaccines to help reduce the burden of disease caused by influenza.”

AFLURIA^® QUADRIVALENT (Influenza Vaccine) Important Safety Information

Indication

AFLURIA QUADRIVALENT is an inactivated influenza vaccine indicated for active immunization against influenza disease caused by influenza A subtype viruses and type B viruses contained in the vaccine. AFLURIA QUADRIVALENT is approved for use in individuals 5 years of age and older.

Contraindications

• Severe allergic reactions (e.g., anaphylaxis) to any component of the vaccine including egg protein, or to a previous dose of any influenza vaccine.

Warnings and Precautions

• If Guillain-Barré Syndrome (GBS) has occurred within 6 weeks of previous influenza vaccination, the decision to give AFLURIA QUADRIVALENT should be based on careful consideration of the potential benefits and risks.
• Appropriate medical treatment and supervision must be available to manage possible anaphylactic reactions following administration of the vaccine.
• Immunocompromised persons may have a diminished immune response to AFLURIA QUADRIVALENT

Adverse Reactions

• In adults 18 through 64 years, the most commonly reported injection-site adverse reaction when administered by needle and syringe was pain (≥40%). The most common systemic adverse events were myalgia and headache (≥20%).
• In adults 65 years of age and older, the most commonly reported injection-site adverse reaction when administered by needle and syringe was pain (≥20%). The most common systemic adverse event was myalgia (≥10%).
• In children 5 through 8 years, the most commonly reported injection-site adverse reactions when administered by needle and syringe were pain (≥50%), redness and swelling (≥10%). The most common systemic adverse event was headache (≥10%).
• In children 9 through 17 years, the most commonly reported injection-site adverse reactions when administered by needle and syringe were pain (≥50%), redness and swelling (≥10%). The most common systemic adverse events were headache, myalgia, and malaise and fatigue (≥10%).

The safety experience with AFLURIA (trivalent formulation) is relevant to AFLURIA QUADRIVALENT because both vaccines are manufactured using the same process and have overlapping compositions:

• In adults 18 through 64 years of age, the most commonly reported injection-site adverse reactions with AFLURIA (trivalent formulation) when administered by the PharmaJet Stratis Needle-Free Injection System were tenderness (≥80%), swelling, pain, redness (≥60%), itching (≥20%) and bruising (≥10%). The most common systemic adverse events were myalgia, malaise (≥30%), and headache (≥20%).
