To produce viral vaccines, candidate vaccine viruses are grown in mammalian, avian or insect tissue culture of cells with a finite lifespan. (wikipedia.org)
The candidate vaccine virus strain will replicate using the mammalian cells. (wikipedia.org)

Cell-based antigen production offer a faster and more stable production of vaccines compared to embryonic chicken eggs, which produce 1-2 vaccine doses per chicken egg. (wikipedia.org)
Though host cells replicate well in chicken eggs, vaccine production with mammalian cells would not rely on an adequate supply of chicken eggs to produce each vaccine. (wikipedia.org)

Serum1
Cell lines grown in synthetic media avoid animal serum, which may pose a sterility problem, more specifically, preventing the spread of transmissible spongiform encephalopathies. (wikipedia.org)
Virus1
Lastly, cell-based vaccines may be more effective given that, with egg-based vaccines, there is a risk that the virus may mutate (antigenic drift) during its long growth phase in the chicken egg, thus causing the immune system to produce a different antibody than originally intended. (wikipedia.org)

Cell-based technology represents one of the most significant changes in the way influenza vaccines are manufactured since the 1940s, and real-world data indicates cell-based flu vaccines may be more effective than standard options in seasons affected by egg-adaptation - in which viruses undergo changes when they are grown in eggs, which may reduce the effectiveness of the resulting vaccines in certain seasons. (pharmatimes.com)
This real-world study, along with other emerging evidence, indicates that cell-based influenza vaccines may result in better influenza-related outcomes compared to standard egg-based vaccine options in some seasons, particularly those seasons characterised by egg-adapted changes," said Russell Basser MD, SVP of Research and Development, Seqirus. (pharmatimes.com)
Lastly, cell-based vaccines may be more effective given that, with egg-based vaccines, there is a risk that the virus may mutate (antigenic drift) during its long growth phase in the chicken egg, thus causing the immune system to produce a different antibody than originally intended.

Seasons1
According to a recent study, which evaluated the degree of match of egg-based and cell-based CVVs to the circulating seasonal virus strain over the past 12 seasons, cell-based H3N2 CVVs have been more closely matched to the circulating virus than the egg-based H3N2 CVVs. (international-pharma.com)
