In celebration of the food and drug administration's (fda) approval of the first cell culture based seasonal influenza vaccine, we wanted to provide a brief overview of the use of cell culture for vaccine manufacturing and a review of our cell culture coverage that includes new technologies, best practices. A novartis vaccines and diagnostics, inc, manufacturing facility in north carolina has geared up to produce pandemic influenza vaccine made from mammalian cell lines, rather than from the traditional chicken egg-based methods that have been used for more than 50 years the plant, open since. We review strategies for optimizing vaccine production with examples given for rabies and influenza using cell culture systems the vero cell line is one of the most satisfactory based on its stability and well-documented performance in quality and quantity of viral yield it has received fda approval and is used throughout. A cell-based flu vaccine was developed as an alternative to the egg-based manufacturing process cell culture technology is potentially more flexible than the traditional technology, which relies upon adequate supply of eggs in addition , the cell-based flu vaccine that uses cell-based candidate vaccine. Rutger van wielink cell culture based production of avian influenza vaccines phd thesis, wageningen university, wageningen, nl, 2012 with summaries in english, dutch and chinese isbn 978-94-6173-353-5. Credit: shutterstock a team of researchers has developed technology that could improve the production of influenza b vaccines by allowing producers to grow vaccine viruses at high yield in mammalian cell culture rather than in eggs led by yoshihiro kawaoka, professor of pathobiological sciences at the. Influenza vaccination is currently the principal means of reducing or counteracting influenza mortality and morbidity burden in the community since the early development of monovalent killed-virus.
A process for making a vaccine for administration to humans or animals comprising: (a) replication of influenza viruses in cell culture, in which mdck 33016 cells (dsm acc 2219) are cultured in cell culture in suspension in serum- free medium, the cells are infected with influenza viruses and after infection. Cell culture production processes are being developed as an alternative to the egg-based influenza vaccine production traditional egg-based production methods are slow and risk supply chain disruptions due to external influences, eg, avian influenza outbreaks, which can leave the human population at risk cell culture. Cell culture-based influenza vaccine production one alternative strategy is to employ cell culture-based production technology, which has been used to generate other vaccines (eg, polio, hepatitis, smallpox, rotavirus, chicken pox)1,6 cell culture technology involves growth of vaccine virus in cultured mammalian cells. “sk chemical has proven its competitive development capability in the cell culture technology currently used in quadrivalent influenza vaccine, among others, and is equipped with a world-standard production facility and capacity,” sanofi spokesperson laurence bollack told biopharma-reporter.
The development and production of a seasonal influenza vaccine each year there is a long lead time to secure chicken eggs every year for the manufacturing of influenza vaccine use of cell culture based influenza vaccine manufacturing eliminates this bottleneck and the possibility of contamination with the avian flu virus. Innovative cell-culture technology potentially allows for quick, efficient production – production of cell-derived vaccine requires little advanced planning and may provide rapid response in the event of pandemic cell-culture process is an innovative and alternative production technique for influenza vaccine manufacturing. Seqirus said it has achieved an industry first by producing a cell-based influenza vaccine on a commercial scale using a virus that has been grown in cells versus the traditional method of use of animal cell cultures versus eggs was approved by the fda for developing seasonal flu vaccines back in 2012.
The recent novel h1n1 pandemic highlighted the need for improved methods that would more rapidly and effectively produce protective influenza vaccines in their article, frey et al  describe a study comparing the standard manufacturing procedure for killed influenza vaccines using hen's eggs to a new cell. These industrially well-established production systems have been primarily selected for a faster and more flexible response to pandemic threats here, we review the most important cell culture manufacturing processes that have been developed in recent years for mass production of influenza vaccines.
Seasonal and pandemic influenza outbreaks require large amounts of vaccine doses to be produced in a timely manner in this regard, cell culture provides one suitable platform for influenza vaccine manufacturing at large-scale moreover, cell culture-based manufacturing systems allow increasing vaccine yields through. . The vaccine is manufactured in only full-scale cell culture influenza vaccine manufacturing facility in the us, in holly springs, nc cell culture technology does not depend on eggs for manufacturing, and the vaccine is produced in sterile bioreactors the change to using cells rather than eggs represented.
Cell-based vaccine is a type of vaccine developed from mammalian cell lines rather than embryonic chicken eggs the potential use of cell culture techniques in developing viral vaccines, especially for the influenza virus, has been widely investigated in recent years as a complementary and alternative platform to the. The cell-culture vaccine is sold under the brand name flucelvax it is made by seqirus it is one of two flu vaccines that are not made in eggs the other, flublok , is made in insect cells it is made by sanofi pasteur experts are also eager to see if flublok worked better this flu season, but generating that data.
Flublok, a trivalent (three-strain) vaccine developed by protein sciences corp of meriden, conn, was approved for adults ages 18 through 49 the only flu virus component it contains is hemagglutinin, the active ingredient, which is produced by infecting cultures of insect cells with a baculovirus that turns. The next generation of influenza vaccines will be cell-culture-based for seasonal influenza and for pandemics leading manufacturers of vaccines and antiviral drugs are working hard to develop new and novel methods of preparing seasonal influenza vaccines, as well as pandemic vaccine candidates. Cell culture-based method for influenza vaccines production offers various advantages over egg-based manufacturing method during influenza pandemics. In previous work, we have shown that hek-293 cell culture in suspension and serum free medium is an efficient production platform for cell culture manufacturing of influenza candidate vaccines this report, took advantage of, recombinant dna technology using reverse genetics of influenza strains, and.
