The NIH director suggested that the cancellation of $500 million in mRNA vaccine contracts was due to public distrust in the technology, a reason that differs from the official explanation of vaccine inefficacy and safety concerns. Despite widespread use and success of mRNA vaccines against COVID-19, some officials and critics question the platform's viability and antigen quantification, though experts argue these concerns are addressed in vaccine science and that continued research is essential for future pandemic preparedness.
