mRNA Vaccine – UPSC Prelims

mRNA Vaccine:
  • mRNA (messenger Ribonucleic Acid) vaccines pave a new era in the realm of vaccine research and development.
  • Traditionally, vaccines incorporate a part of a harmless pathogen in the body against which the antibodies are targeted.
  • In case of mRNA vaccines, the mRNA molecules of the pathogen (SARS-CoV-2 mRNA in case of the COVID-19 virus) are used to activate the immune system to combat the virus and other infectious agents.
  • This vaccine has been developed with an approach that ensures a significant immune response along with safety.
  • The researchers emphasised on the fact that minimising the injection of a foreign body results in reduced possibility of adverse reactions.
  • Therefore in mRNA vaccines, a piece of genetic code is introduced into the body of the individuals to trigger immune responses. The genetic code corresponds to the viral protein present on the outer membrane of the virus.
