The genomic evolution of the virus presumes that the novel SARS-CoV-2 has altered its genetic structure and now has different implications on people’s health. The SARS virus did not have such virulence and the ability to be transferred from person to person. Earlier, the infected population suffered from severe pneumonia; there was an immediate understanding that the person was seriously ill, whereas now people have no visible symptoms at first.
Vaccination and immunizations are widely implemented for halting any contagious disease and its spread. Vaccines have been in use for many years to protect the world’s population from viruses, especially those that are spread by airborne droplets.
Developing a vaccine may take up to several decades, depending on the virus and its viability. However, modern technologies allow for faster progress and guarantee more effectiveness of the vaccine. The innovation is not the sole key to implementing a vaccine since it is vital to test it on animals and candidates to check its potential.
These groups should get injections against COVID-19 first because they are mostly exposed to the virus transmission.
Genetic encoded vaccine
The genetic encoded vaccine implies that the genetic material of the pathogen of the disease is introduced into the body. On the basis of the information available in it, the body synthesizes an antigen, that is, a part of the pathogen necessary for the emergence of immunity.
The vaccine is expected to be used in the form of drops or spray in order to remove a strain from the hospitals and other facilities providing vaccinations. Such forms of vaccines are likely to increase the number of people who are ready to prevent themselves from a virus.
