University of California, Riverside scientists are studying whether they can turn edible plants like lettuce into mRNA vaccine factories. If this new project is successful, plant-based mRNA vaccines, which can be eaten, would enable the vaccines to be stored at room temperature.

Prelims question:

Consider the following statements regarding mRNA vaccines:

  1. mRNA vaccines tricks the body into producing some of the viral proteins itself.
  2. mRNA vaccines are fully synthetic and do not require a host for growth.
  3. These vaccines can interact with our DNA and thus are not considered safe.

Which of the above statements are correct?

  • A.
  • B.
  • C.
  • D.

Mains Question:

What are mRNA vaccines? What advantages does mRNA vaccine technology provide over other conventional vaccine technologies? (150 Words)
