As mRNA technology expands beyond COVID-19 into new products such as Moderna’s recently approved mRNA influenza vaccine, questions about the long-term implications of genetic medicines have become increasingly relevant. An Orthodox Cytogeneticist Explores Scientific Threats to Human Health and DNA examines these developments through the perspective of licensed cytogeneticist Vasily Maltsev. The article explores mRNA technology, DNA integrity, epigenetics, gene editing, artificial intelligence, pharmaceutical influence, and concerns surrounding SV40 promoter sequences used in plasmid manufacturing. It argues that the rapid expansion of genetic technologies warrants greater transparency, independent scientific scrutiny, and ethical accountability before broader adoption. Combining professional expertise with Orthodox Christian teaching, the article challenges readers to consider whether modern biotechnology adequately protects human health, safeguards the human genome, and respects the God-given dignity of the human person. An essential read for anyone interested in mRNA vaccines, genetics, bioethics, public health, and the intersection of Orthodox Christianity and modern science.
