Q. Which of the following is/are the advantages of mRNA Vaccines?
1.Non-infectious, non-integrating in nature
2.Highly efficacious compare to other vaccines
3.Do not require a host for growth
Select the correct answer from the codes given below;

[A] 1 and 2 only

[B] 2 and 3 only

[C] 1 and 3 only

[D] 1, 2 and 3

Answer: D
Notes:

The major advantages of mRNA vaccines are,

  1. They are non-infectious, non-integrating in nature, and degraded by standard cellular mechanisms.
  2. Highly efficacious because of their inherent capability of being translatable into the protein structure inside the cell cytoplasm.
  3. mRNA vaccines are fully synthetic and do not require a host for growth, e.g., eggs or bacteria. Therefore, they can be quickly manufactured inexpensively to ensure their “availability” and “accessibility” for mass vaccination on a sustainable basis.
