The efficacy of Abdala (92.8%) is to prevent the symptomatic disease: covid-19. Vaccines prevent, in a percentage, that the person is infected; in another percentage, they prevent the person from becoming ill, from reaching seriousness or a critical or serious state of the disease; and in another percentage, they prevent the person from dying. In clinical studies, Abdala was 100% effective in preventing death; 100% efficient to get to gravity; and a lower percentage (92.8%) to avoid symptomatic disease.
