Making Better Influenza Virus Vaccines? (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)
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)
Vaccines produced by chemical inactivation of virus are available, but there are concerns about their safety and they do not induce protection prior to about 7 days postvaccination. (usda.gov)
As noted by Mikovits, we now know that the worst symptoms of COVID-19 are created by the SARS-CoV-2 spike protein , and that is the very thing these gene-based vaccines are instructing your body to make. (fromthetrenchesworldreport.com)
But it's far worse, as the vaccines do not cause your body to make the same spike protein as SARS-CoV-2 but one that has been genetically modified, making it far more toxic. (fromthetrenchesworldreport.com)
