Summary
Prophylactic vaccines against oncogenic infections like HPV and HBV significantly reduce cancer incidence. Continued research and improved vaccination coverage are crucial for global cancer prevention, especially in low-resource settings.
Area of Science:
- Oncology
- Infectious Diseases
- Vaccinology
Background:
- Oncogenic infections contribute significantly to the global cancer burden, particularly in low- and middle-income countries.
- Prophylactic vaccination is a key strategy for preventing infection-related cancers, including those caused by human papillomavirus (HPV) and hepatitis B virus (HBV).
Purpose of the Study:
- To review the impact, advances, limitations, and future prospects of current and developing cancer vaccines.
- To synthesize recent data on the effectiveness of prophylactic vaccines against oncogenic infections.
Main Methods:
- This narrative review synthesizes recent data from published studies on cancer vaccines.
- The review focuses on the impact of HPV and HBV vaccination and discusses ongoing vaccine development for other oncogenic agents.
Main Results:
- HPV vaccination demonstrably reduces infections, precancerous lesions, and invasive cancers, with greater efficacy at high coverage and early administration.
- Universal HBV vaccination has successfully decreased chronic infections and hepatocellular carcinoma rates.
- Several prophylactic vaccines against oncogenic agents like EBV, H. pylori, and HCV are in development, utilizing novel platforms such as mRNA.
Conclusions:
- Vaccination against oncogenic HPV and HBV is highly effective in preventing associated cancers.
- Challenges such as access, cost, and vaccine coverage must be addressed to maximize global impact.
- Ongoing research and development of new cancer vaccines hold significant promise for future cancer prevention strategies.

01:30Cancer Vaccines
Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

02:59Cancer Prevention
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

01:27Tumor Immunotherapy
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
01:30Preventive Healthcare Services
Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:
02:18Cancer
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
