Not if it’s the new untested gene based one. i won’t as that could have real bad effect on your cells and could start attacking other cells. one has to understand a little about the immune system. to understand why. Pretty much like , the problems they are coming across is stem cells can cause the cells to turn cancerous when they try to create them from human cells already in the body.. we do not have stem cells. https://lymphoma-action.org.uk/about-lymphoma-what-lymphoma/immune-system explains how the immune system works. In austrailia sky news was saying they will not be giving the vaccine to those at high risk or children as it is not safe. Gene therapy is an experimental technique that uses genes to treat or prevent disease. In the future, this technique may allow doctors to treat a disorder by inserting a gene into a patient’s cells instead of using drugs or surgery. Sounds alot how the vaccines works Current antiviral vaccine designs can be described as falling into 2 camps: protein based or gene based. Protein-based vaccines deliver the immune system–stimulating antigen to the body. This category includes whole-inactivated (killed) vaccines, as in the polio and flu shots, and subunit vaccines and virus-like particles, like in the hepatitis B and human papillomavirus vaccines. or much cheaper to make. Gene-based vaccines take a different tack. They carry the genetic instructions for the host’s cells to make the antigen, which more closely mimics a natural infection. In the case of coronaviruses, the antigen of interest is the surface spike protein the virus uses to bind and fuse with human cells. “You’re not giving them the protein—you’re giving them the genetic material that then instructs them how to make that spike protein, to which they make an antibody response that hopefully is protective. only thing is the human body may kill off those infected host cells and others.
The mRNA vaccine in question being the Pfizer offering of course.
What’s being used is “an instruction sheet” on how to make the spike protein, it will be taken up by some cells & the spike protein will be produced in limited quantity for a limited time until the mRNA is broken down by the cells it enters. It doesn’t mean that the mRNA will be translated into DNA & incorporated into the human genome, just that the mRNA will be read, antigens produced & the body mounts a reaction by producing antibodies.
Yes the body will kill off cells producing viral antigens, and you’ll be a few cells less for a few days until new ones are made to replace them. This is exactly what will happen if you get COVID-19 anyway, your body will hopefully find & destroy any infected cells.
