    Why is it difficult to make a vaccine for the coronavirus?

    In the human body, hereditary traits are transmitted by a ladder-shaped, twisted molecule called DNA. During cell division, the two strands of DNA separate, and a new copy is made from each strand. In this way, each new cell will have a single strand of DNA molecule in the nucleus. During the fabrication of DNA strands, a modifying agent confirms the accuracy of the molecule made. If the genetic mutations are produced incorrectly in the DNA, what is produced will fail. However, many viruses, such as coronaviruses, have a single-stranded molecule called RNA instead of DNA. These viruses transmit hereditary traits to new viruses by the same RNA.
