The jointwork of researcherswho have analyzed the COVID-19 cases, the biological mechanisms, their effects on human beings, and possible intervention pathways have led to successful scientific advances in the understanding of the infection, the creation of immunity, the use of specific medications, in addition to an innovative and historical way of creating new vaccines that are both efficient and safe. It is also crucial to note that the effort to produce positive results involves the continued used of safety precautions such as handwashing, surface disinfection, social distancing and protective equipment, among others.
