Messenger RNA vaccine scepticism is based on concerns that mRNA will cause permanent changes to a person's DNA. But coronaviruses, and the mRNA vaccine like it, uses the body's innate protein production mechanism and doesn't interfere with the cells nucleus or the body's DNA sequence. On the other hand mRNA vaccines offer advantages over traditional vaccines, for being faster and cheaper to produce, and this is why they seemed the most promising solution for public health bodies and biotechnology companies. The UK's Medicines and Healthcare products Regulatory Agency (MHRA) were the first to approve this technology for use in humans, and MHRA CEO June Raine said "no corners have been cut in approving it ... the benefits outweigh any risk".
