Abstract

Coronavirus is a group of viruses that causes a variety of respiratory pathologies from the common cold to more serious diseases such as pneumonia, Middle East Respiratory Syndrome (MERS), and Severe Acute Respiratory Syndrome (SARS-COV-2-2). The respiratory disease caused by this virus generates high morbidity in all age groups, with a high mortality in people over 60 years of age with comorbidities. This implies that, although there are no fatal outcomes in potentially productive groups of the population, it does generate high disability, and in some cases, a certain degree of impairment due to consequences attributable to the infection that has a high economic impact in low and middle-income countries like Colombia. One of the most cost-effective strategies for the prevention of viral diseases is vaccines. With the approval of the World Health Organization, these have become one of the most important technologies in the control of the disease, Covid-19. Considering the speed with which biologics were produced and based on the urgent need for their widespread use, studies are required to help support their effectiveness. In this narrative review of the literature, the effectiveness rates reported in the different countries of the American continent were compared, as well as the possible factors that could influence those results.
