Flulaval Quadrivalent Influenza Vaccine Description 2022

GSK's Flulaval Quadrivalent is an inactivated influenza virus vaccine prepared from viruses propagated in hens’ eggs. Each of the four influenza viruses is produced and purified separately. The viruses are inactivated with ultraviolet light treatment followed by formaldehyde treatment, purified by centrifugation, and disrupted with sodium deoxycholate.

Flulaval Quadrivalent is formulated without preservatives and does not contain thimerosal, says the U.S. FDA. STN: BL 125163.

The WHO has announced the composition of the flu vaccine for the 2023 southern hemisphere flu season.

The U.S. CDC says 'Flulaval for 2021-2022, quadrivalent (four-component) egg-based vaccines is recommended to contain: A/Victoria/2570/2019 (H1N1)pdm09-like virus, A/Tasmania/503/2020 (H3N2) IVR-221 (A/Cambodia/e0826360/2020 (H3N2)-like virus), B/Washington/02/2019 (B/Victoria lineage)-like virus, and B/Phuket/3073/2013 (B/Yamagata lineage)-like virus.'

GlaxoSmithKline plc (GSK) is located in Brentford, United Kingdom.

Flulaval Quadrivalent Indication

Flulaval Quadrivalent is indicated for active immunization to prevent disease caused by influenza A subtype viruses and type B viruses contained in the vaccine.

Flulaval Quadrivalent and COVID-19 Vaccines

The US Centers for Disease Control and Prevention (CDC) previously issued interim clinical considerations stating that 'COVID-19 vaccines and other vaccines, including influenza vaccines, can be administered without regard to timing. And the annual influenza vaccination is recommended for all persons aged 6 months and older who do not have contraindications. 'Providers should be aware of the potential for increased reactogenicity with coadministration and should consult the CDC for updated guidance as more information becomes available. If coadministered, COVID-19 vaccines and vaccines that might be more likely to cause a local reaction (e.g., aIIV4 or HD-IIV4) should be administered in different limbs, if possible.'

'No data are currently available concerning coadministration of currently Authorized COVID-19 vaccines and influenza vaccines,' stated Lisa Grohskopf, M.D., MPH, CDC's ACIP vaccine committee presentation (slide #14) on June 24, 2021.

Flulaval Quadrivalent Dosage

Flulaval Quadrivalent is approved for use in persons aged 6 months and older. Flulaval Quadrivalent is administered as an intramuscular injection.

Do not administer Flulaval Quadrivalent to anyone with a history of severe allergic reactions (e.g., anaphylaxis) to any component of the vaccine, including egg protein, or following a previous dose of any influenza vaccine.

Flulaval Quadrivalent Side Effects

Flulaval Quadrivalent is generally well-tolerated. However, if you or your loved one has an adverse reaction to the vaccine, that information should be reported to VAERS.

VAERS is a U.S. passive reporting system, meaning it relies on individuals to send in reports of their experiences to a vaccine. Anyone can submit a report to VAERS, including parents and patients. Furthermore, healthcare providers are required by law to report to VAERS.
