The rapid development and deployment of mRNA vaccines in 2020 marked a groundbreaking advancement in immunology and biotechnology, particularly in response to the COVID-19 pandemic. These vaccines, which use messenger RNA to instruct cells to produce a harmless piece of the virus, elicited a strong immune response with high efficacy. This innovative approach not only provided a swift solution to a global health crisis but also opened new avenues for vaccine development against various diseases.

The success of mRNA technology has influenced contemporary discussions on science communication and trust, appearing in literary works that explore the intersection of data, biology, and public discourse, and the poetic potential of genetic language. Poets like Tracy K. Smith have begun to engage with these themes, reflecting on the implications of scientific advancements for society.
