For 2021-2022, the U.S. FDA identified quadrivalent (four-component) egg-based vaccines are recommended to contain: an A/Victoria/2570/2019 (H1N1)pdm09-like virus; an A/Cambodia/e0826360/2020 (H3N2)-like virus; a B/Washington/02/2019 (B/Victoria lineage)-like virus; a B/Phuket/3073/2013 (B/Yamagata lineage)-like virus.
For 2022-2023 the WHO recommends that egg-based quadrivalent vaccines contain the following viruses. An A/Victoria/2570/2019 (H1N1)pdm09-like virus, an A/Darwin/9/2021 (H3N2)-like virus, a B/Austria/1359417/2021 (B/Victoria lineage)-like virus, and a B/Phuket/3073/2013 (B/Yamagata lineage)-like virus.
And the WHO just announced the recommended composition for the influenza virus vaccines for the 2023 southern hemisphere influenza season.
The FDA Vaccines and Related Biological Products Advisory Committee announced on March 3, 2022, the influenza vaccine strains for the 2022-2023 flu season in the Northern Hemisphere.

Afluria Quadrivalent Vaccine Price
Seqirus USA, Inc provides a coding and billing guide for health care providers. The CDC vaccine price list indicates this flu shot will range from $18.52 to $20.03.
The U.S. CDC confirmed the Vaccines For Children program is a federally funded program that provides vaccines and medicines at no cost to children. And InstantRx™ is a digital gateway empowering people to easily find lower-priced medicines and vaccines.
Afluria Quadrivalent Indication
Afluria Quadrivalent is indicated in people 6 months of age and older for active immunization against influenza disease caused by influenza A subtype viruses and type B viruses contained in the vaccine.
On July 27, 2021, Gregg Sylvester, M.D., Chief Medical Officer at Seqirus, stated in a press release, “With our rich history and exclusive focus on influenza, we know that influenza vaccination can save lives and is an important step we can take to help protect ourselves, our loved ones and our communities. A continued focus on influenza vaccination is critically important because, while rates of influenza were generally low last season, we cannot assume this will be the case during the coming year, and we need to be prepared."
Afluria Quadrivalent and COVID-19 Vaccines
The US Centers for Disease Control and Prevention 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.
Afluria Quadrivalent Dosage
Afluria is administered as an intramuscular injection by needle and syringe (6 months+) or by PharmaJet®Stratis® Needle-Free Injection System (18 through 64 years).
Store AFLURIA QUADRIVALENT refrigerated at 2°C to 8°C (36°F to 46°F). Protect from light. Do not freeze. Discard if the vaccine has been frozen. Do not use it after the expiration date.
Afluria Quadrivalent Side Effects
Afluria 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.
