Public perception of mRNA vaccines

The development of mRNA technology marks one of the most groundbreaking moments in modern medicine. Once relegated to experimental laboratories, it emerged as a beacon of hope during the COVID-19 pandemic, enabling the rapid creation of highly effective vaccines. Pfizer’s BNT162b2 and Moderna’s mRNA-1273 vaccines were hailed as marvels of science, offering unprecedented efficacy in preventing severe illness and death. However, as the pandemic’s urgency recedes, a more nuanced reality surfaces: trust in these innovations is alarmingly tenuous. The revolution in science meets reality of distrust Recent research has undertaken the challenge of charting global sentiment toward mRNA vaccines and therapeutics by analyzing public conversations on Twitter. Utilizing advanced tools such as large language models (LLMs) and machine learning, the study examined over 740,000 tweets posted between June 2022 and May 2023. The results reveal a concerning trend—negative sentiments dominate the discourse, with 69.5% of tweets expressing skepticism or distrust. Safety...
