How Influenza (Flu) Vaccines Are Made | CDC - Centers for Disease ...
WEBEgg-based vaccine manufacturing is used to make both inactivated (killed) vaccine (usually called the “flu shot”) and live attenuated (weakened virus) vaccine (usually called the “nasal spray flu vaccine”).
Viral vector vaccine - Wikipedia
WEBA viral vector vaccine is a vaccine that uses a viral vector to deliver genetic material that can be transcribed by the recipient's host cells as mRNA coding for a desired protein, or antigen, to elicit an immune response. [1]
Key Facts About Seasonal Flu Vaccine | CDC - Centers for Disease ...
WEBMar 22, 2024 · Influenza (flu) vaccine effectiveness (VE) can vary. The protection provided by a flu vaccine varies from season to season and depends in part on the age and health status of the person getting the vaccine and the similarity or “match” between the viruses in the vaccine and those in circulation.

WEBAug 7, 2014 · Recombinant virus-vectored vaccines are an appealing alternative to classical inactivated vaccines because virus vectors enable native expression of influenza antigens, even from virulent influenza viruses, while expressed in the context of the vector that can improve immunogenicity.
Progress on adenovirus-vectored universal influenza vaccines
WEBRecombinant adenovirus (rAd) is an ideal influenza vaccine vector because it has an ideal stability and safety profile, induces balanced humoral and cell-mediated immune responses due to activation of innate immunity, provides 'self-adjuvanting' activity, can mimic natural IFV infection, and confers seamless protection against mucosal pathogens.
