Vaccination and Therapeutics.

In the wake of the novel Coronavirus, it has become imperative to develop vaccines that can alert our immune system to the virus, hence reducing the severity of disease if exposed to it. Different types of vaccines have been studied in this respect, such as nucleic acid vaccines (mRNA and DNA vaccines), vector-based vaccines, whole-virus vaccines (inactivated virus and live-attenuated vaccine), as well as protein subunits vaccines. The results have demonstrated that these vaccines are efficient against both the original strain and emerging variants. Furthermore, they also proved their safety with no grave adverse events. Despite this, hesitancy toward taking these vaccines is still present among certain groups in society due to various factors. Special emphasis has been placed on studies concerning pregnant women, children, elderly people, and immunocompromised individuals where efficacy and safety were proven.
