How do mRNA vaccines work?
How do mRNA vaccines work?
- They introduce a weakened or inactivated version of the pathogen into the body
- They contain the genetic instructions for producing proteins in our own cells (correct)
- They mimic an infection and train the immune system to recognize a disease-causing agent
- They contain the virus itself in the vaccine
Why were mRNA vaccines a long-standing ambition for scientists?
Why were mRNA vaccines a long-standing ambition for scientists?

- They contain the virus itself in the vaccine
- They were hoped to offer many advantages over traditional vaccines (correct)
- They contain the genetic instructions for producing proteins in viruses
