However, no research study has shown that.<\/p>\n

But science is not based on one single study. Science is a process: a careful, ongoing way of learning about the world. Scientists test ideas, gather data, and repeat experiments to see if results hold up. When many experts review the evidence and come to similar conclusions, that\u2019s called scientific consensus. This consensus helps guide public health decisions and medical advice.<\/p>\n

This claim sometimes comes from a concern\u00a0that\u00a0mRNA vaccines could change our DNA to\u00a0cause cancer. But scientists have found no evidence that vaccines do either of these things.<\/p>\n

Dr. Paul Offit<\/a>\u00a0explains that it\u2019s nearly impossible for the tiny bits of genetic material (or\u00a0DNA fragments) that may be present in vaccines to cause harm. Our cells have several built-in protection systems that make this kind of thing impossible:<\/p>\n

    \n
  1. Our cells destroy foreign DNA.<\/strong>\u00a0Inside our cells is a jelly-like area called the\u00a0cytoplasm<\/em>. It contains immune defenses and special proteins called\u00a0enzymes<\/em>\u00a0that quickly break down any DNA that doesn\u2019t belong there.<\/li>\n
  2. DNA fragments can\u2019t reach our genes.<\/strong>\u00a0Our DNA is stored safely inside a part of the cell called the\u00a0nucleus<\/em>. The DNA fragments from vaccines don\u2019t have the \u201centry code\u201d needed to get through the wall that protects the nucleus.<\/li>\n
  3. They can\u2019t attach to our DNA.<\/strong>\u00a0Even if a fragment could reach the nucleus, it would still need a special enzyme called\u00a0integrase<\/em>\u00a0to stick to our genes. The vaccine doesn\u2019t contain this enzyme, so it\u2019s like trying to glue something without any glue. It simply doesn\u2019t work.<\/li>\n<\/ol>\n

    For these reasons, experts are confident that vaccines do\u00a0not<\/strong>\u00a0cause cancer.<\/p>\n

    In fact, some research has suggested the opposite of what the tweet claimed. Certain\u00a0studies<\/a>\u00a0suggest that mRNA vaccines,\u00a0<\/em>like the ones used for COVID, could help the immune system recognize and attack cancer cells more effectively. Scientists are even studying how mRNA technology might be used in future cancer treatments. And we all hate cancer<\/a>.[\/vc_column_text][\/vc_column][\/vc_row]\n<\/div>","protected":false},"excerpt":{"rendered":"
