Afluria Quadrivalent Influenza Vaccine 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 Influenza Vaccine 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 Influenza Vaccine Dosage
