Abstract:
Cancer remains one of the global leading causes of death and various vaccines have been developed over the years against it, including cell-based, nucleic acid-based, and viral-based cancer vaccines. Although many vaccines have been effective in in vivo and clinical studies and some have been FDA-approved, there are major limitations to overcome: (1) developing one universal vaccine for a specific cancer is difficult, as tumors with different antigens are different for different individuals, (2) the tumor antigens may be similar to the body's own antigens, and (3) there is the possibility of cancer recurrence. Therefore, developing personalized cancer vaccines with the ability to distinguish between the tumor and the body's antigens is indispensable. This paper provides a comprehensive review of different types of cancer vaccines and highlights important factors necessary for developing efficient cancer vaccines. Moreover, the application of other technologies in cancer therapy is discussed. Finally, several insights and conclusions are presented, such as the possibility of using cold plasma and cancer stem cells in developing future cancer vaccines, to tackle the major limitations in the cancer vaccine developmental process.
Insights
Developing personalized cancer vaccines is crucial to overcome limitations of current approaches, such as tumor heterogeneity and recurrence. Future vaccines may utilize cold plasma and cancer stem cells for improved efficacy.
Area of Science:
- Oncology
- Immunology
- Biotechnology
Background:
- Cancer is a leading global cause of death, driving the development of various vaccine types.
- Existing cancer vaccines (cell-based, nucleic acid-based, viral-based) show promise but face significant limitations.
- Challenges include tumor antigen diversity, self-antigen mimicry, and cancer recurrence, hindering universal vaccine development.
Purpose of the Study:
- To comprehensively review current cancer vaccine types and their developmental factors.
- To highlight the necessity of personalized cancer vaccines that can differentiate tumor from self-antigens.
- To discuss emerging technologies for advanced cancer therapy.
Main Methods:
- Literature review of existing cancer vaccine strategies.
- Analysis of key factors for developing effective cancer vaccines.
- Exploration of novel technologies like cold plasma and cancer stem cells.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
