With Covid-19 a lot of problems affected our daily life and society, and with those same problems, a lot of paranoia also came along. We experienced empty markets and a lot of misconceptions, but the worst came after. For reasons I cannot comprehend people started sharing this "idea" that the Covid-19 vaccine's true purpose was to "alter" our DNA. The truth is that, as we know, vaccination consists of stimulating our immune system by injecting an infectious agent or a component of one that has been modified so that no harm will happen to the person receiving the vaccine. DNA vaccines inject the plasmid that contains the DNA sequences that include the antigen or antigens to which we seek a response. This method comes with some advantages like improved vaccine stability and the absence of any infectious agent, although this is still a method that is rapidly developing. The thing is that DNA vaccines don't introduce any DNA into our cells' nucleus, so our own DNA remains unaffected. In the end, the claim that the vaccine for Covid-19 will affect our DNA is just a claim against a developing vaccination technique that, as we said earlier, doesn't harm or "alters" us in any manner.
