“Another way is via genetic engineering. Here the germ is inserted into plasmid that has been manipulated by scientists. This type of plasmid is circular segments of DNA extracted from bacteria to serve as a vector. Scientists can add multiple genes and whatever genes they want into this plasmid. In case of vaccines, this includes a genetic piece of the vaccine germ and normally a gene for antibiotic resistance. This means that when the toxic gene is cultured inside the yeast, it has been designed with a new genetic code that makes it resistant to the antibiotic it’s coded for. The gene-plasmid combo is inserted into a yeast cell to be replicated. When the yeast replicates, the DNA from the plasmid is reproduced as a part of the yeast DNA. Once enough cells have been replicated, the genetic material in the new and improved yeast cell is extracted and put into the vaccine. Examples of this vaccine are the acellular pertussis and hepatitis B vaccines. One thing that doesn’t seem to concern scientists is the fact that the manmade genetic combination becomes the vaccine component. This mixture of intended and unintended genetic information may cause our immune system to overreact. This can be especially complicated for a child with compromised immune system. Another concern is that this new genetic code can become integrated with our own genetic material. Yeast, for instance, is very much like human DNA. It shares about one third of our proteins.”
