The cancer vaccine is introduced as a unique approach to cancer therapy. It naturally exerts an anti-tumor effect after engaging the host immune response. In addition to that, it potentially circumvents the resistance of an intrinsic drug limiting standardized cancer management. Among additional advantages of cancer vaccine include low toxicity, exquisite specificity, & potentiality for a reliable & durable effect in treatment brought by immunologic memory.
Being an immunotherapy form, it helps in educating the immune system of the appearance of cancer cells. This is the only way that the immune system will recognize and best eliminate them.
Truly, a vaccine is effective in the prevention of diseases brought about by bacteria and viruses. The first vaccine was created two-hundred years ago. It has helped prevent the deadliest diseases of the twentieth century. Plus, it saved thousands to millions of lives around the world.
The vaccine is indeed useful in exposing people to an inactivated or weakened version of the threat. It enables the immune system to identify certain threats based on their specific markers or the so-called antigens. Then, it mounts a specific response against them. This vaccine works the best way possible in such a preventive setting. This is true when an individual is provided the vaccine before the injection of virus or bacteria.
Regarding cancer, the situation is more difficult for so many reasons. This just ended up developing vaccines in the more difficult way. This is regarding the treatment or prevention of cancer. And unlike viruses and bacteria that appear foreign to the immune system, the cancer cells resemble more closely healthy and normal cells. Every tumor found in an individual is sort of unique. It also comes with its distinguishing antigens. This is why more sophisticated approaches are needed in developing an effective cancer vaccine.
Cancer Vaccine Sort of a Preventive Method
Viral infections are the main reason why several cancers are developed. Preventive vaccines then play an essential role in the reduction of risk. For one, neck and head cancer, and cervical cancer can be brought by the human papilloma virus or the HPV. Similarly, liver cancer can also be attributed to hepatitis B or the HBV.
More vaccines are also underway in their development preventing HPV and HBV infections. They indeed have a role to play in the protection of HPV- and HBV-related cancers. In fact, four cancer preventive vaccines have been suggested by the Food and Drug Administration of the United States.
Cancer Vaccine for Therapeutic Purposes
It ever has been mentioned that each tumor of an individual is unique. It also comes with specific and distinguishing antigens. This is when more sophisticated approaches to cancer vaccines are needed.
The good thing is that doctors can easily identify the targets on the tumors of patients. These can help distinguish the cancer cells from the normal cells. The targets are often normal proteins produced at higher levels by the cancer cells. These can include the prostatic acid phosphatise or PAP. This is so far over-expressed by the prostate cancer cells.
This is when the sipuleucel-T vaccine is developed. It is then received under the approval of the FDA in 2020. This goes perfectly for the treatment of patients having an advanced form of prostate cancer. The virus-derived protein is expressed by the cancer cells infected by the virus provider for another promising marker. This can easily be targeted by using vaccines.
Nevertheless, understand it still that cancer vaccines come with side effects. It may also be influenced clearly by the type of cancer and the location and the overall health. Patients need to consult a medical care team in gaining a fuller and better understanding of the potential side effects and risks linked with cancer vaccines.
Now, you have learned more about cancer vaccine Thailand that is now introduced as a unique method for cancer therapy!
