Can mRNA vaccines do for cancer what they did with Covid-19? (medcitynews.com)

key points:

* mRNA vaccines aren't a silver bullet for cancer, but may help when paired with other therapeutic modalities.

* cancer and covid are different. covid is far simpler because vaccines can target a single antigen, the spike protein.

* by contrast, many tumors mutate and over time evade single-antigen vaccines. moreover, different tumors may exhibit different antigens so what works for one cancer type may not translate to another. lastly, vaccines require cooperation from the immune system. even if researchers identify a promising antigen, there's no guarantee the immune system will recognize this antigen and act against the tumor.

* in summary, one of the hardest questions when developing cancer vaccines is defining which antigens to target.

terms (from wikipedia):

* antigen: a molecule or molecular structure, that may be present on the outside of a pathogen, that can be bound by an antigen-specific antibody or B-cell antigen receptor. The presence of antigens in the body normally triggers an immune response.

thanks. i can’t delete this for some reason.

dang, if you see this, please delete this so we can concentrate discussion on the home page thread.

Perhaps this is naive but i don't think that would apply in the cancer case. I assume it wanes for covid because the body slows down anti-body production after it appears that there is no more disease (well still remembering how so it can ramp up quickly, ramp up quickly is much better than start from scratch but not as good as antibodies already ready). I assume for cancer that wouldn't happenunless cancer is gone. However it would maybe wane for other reasons discussed in the article.

Can anyone tell me, what have the vaccines done for us already? Because they don't seem to work, so I hope in the search of healing cancer (a metabolic disease) they opt for something different. It seems like a waist of time and money, at least mine.


dont seem to work?

AZ,PFZ,MDRNA all work quite well.

They MASSIVELY reduce the potential damage getting infected can do. They also reduce the chances of getting infected.

is this not enough?
