The main benefit of cell-based vaccines is the ability to rapidly produce vaccine supplies during an impending pandemic.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. [8]
Production of a single year's supply of human growth hormone required up to fifty pituitary glands, [3] creating significant shortages of the hormone. [4] In 1979, scientists at Genentech produced human growth hormone by inserting DNA coding for human growth hormone into a plasmid that was implanted in Escherichia coli bacteria.
The process of serial passage yields a live vaccine. There are both advantages and disadvantages to this. Most notably, live vaccines are sometimes more effective and more long-lasting than inactivated or other types of vaccines. [10] [11] However, just as the virus evolved to become attenuated, it may reverse-evolve in the host, leading to ...
With the discovery of various types of immune-related disorders, there is a need for diversification in prevention and treatment. Developments in the field of gene therapy are being studied to be included in the scope of this treatment, but of course more research is needed to increase the positive results and minimize the negative effects of gene therapy applications.

A Memorial Sloan Kettering phase 1 clinical trial revealed an immune response in some pancreatic cancer patients. Study co-author Dr. Vinod Balachandran talks about the impact on future cancer care.
The vaccines do not contain any of the original fetal tissue or cells or cells derived from fetal materials. [5] Although the vaccine materials are purified from cell debris, traces of human DNA fragments remain. [6] [7] [8] The cell lines continue to replicate on their own and no further sources of fetal cells are needed. [5]
