How mRNA Vaccine works - teaching our cells to make their own vaccine​

The vaccine spurs healthy cells to produce viral proteins that stimulate a potent immune response.

  • mRNA can be quickly designed and scaled up. The manufacturing is sequence-independent, which makes it highly adaptable to different pathogens.
  • Cost: The cost is also lower than other platforms and will continue to decrease as the technology expands.
  • Safety: Other vaccines such as protein-based or inactivated vaccines require chemicals & cell cultures to produce. mRNA is made through a cell-independent process and does not require inactivation; thus, it poses no safety concerns due to contamination with toxic agents.
  •   More effective immune response.
  • Unlike live-attenuated or viral-vectored vaccines, mRNA is non-infectious and poses no concern for DNA integration—mainly because it cannot enter the nucleus which contains DNA.
