Making Better Influenza Virus Vaccines? (cdc.gov)
Killed and live influenza virus vaccines are effective in preventing and curbing the spread of disease, but new technologies such as reverse genetics could be used to improve them and to shorten the lengthy process of preparing vaccine seed viruses. (cdc.gov)
By taking advantage of these new technologies, we could develop live vaccines that would be safe, cross-protective against variant strains, and require less virus per dose than conventional vaccines. (cdc.gov)
Furthermore, pandemic vaccines against highly virulent strains such as the H5N1 virus can only be generated by reverse genetics techniques. (cdc.gov)
Finally, universal influenza virus vaccines seem to be within reach. (cdc.gov)
These new strategies will be successful if they are supported by regulatory agencies and if a robust market for influenza virus vaccines against interpandemic and pandemic threats is made and sustained. (cdc.gov)
Influenza virus vaccines were first developed in the 1940s and consisted of partially purified preparations of influenza viruses grown in embryonated eggs. (cdc.gov)
This technology, which originated from uses for military purposes, revolutionized the purification process and industrial production of many viruses for vaccines. (cdc.gov)
To this day, it remains the basis for the manufacturing process of our influenza virus vaccines. (cdc.gov)
Also, because the cumbersome classical reassortment technique used for preparing the appropriate seed strains makes the yearly process of manufacturing influenza virus vaccines unnecessarily lengthy, new variants first appearing early in the season are rarely considered for the vaccine formulation of the following winter. (cdc.gov)
Most influenza virus vaccines used in the United States and Europe consist of embryonated egg-grown and formaldehyde-inactivated preparations, which, after purification, are chemically disrupted with a nonionic detergent (for example, Triton X-100). (cdc.gov)
The split virus preparations show lower pyrogenicity than whole virus vaccines. (cdc.gov)
For example, the production of virus-based vaccines, recombinant proteins using viral vectors, and viral antigens all require virus quantification to continually monitor and/or modify the process in order to optimize product quality and production yields and to respond to ever changing demands and applications.
