Integer Hospitalization_and_outcome Information about the participant's hospitalization and the outcome of the hospitalization. Integer Outcome The outcome of the patient, whether there was death or not. String Before_d1 Information about the patient's condition before the first dose of the vaccine. Float Severity_before The measure of the severity of the participant's condition before the first dose of the vaccine. Float t_hospitalized_before The amount of time the participant spent hospitalized before the first dose of the vaccine.

Float Date_of_death The date on which the patient died, if applicable. Date Immunization Information about the patient's immunization for example HD - Half Dose and FD - Full Dose String Comorbidity Whether the patient has any pre-existing medical conditions or not. String This database contains information about the administration of the ChAdOx1 nCoV-19 vaccine in half doses and its equivalence in reducing moderate and severe cases of COVID-19 compared to full doses. The ChAdOx1 nCoV-19 vaccine is developed to prevent infection by the SARS-CoV-2 virus, which causes COVID-19. The study analyzed the efficacy of administering the vaccine in half doses compared to full doses. The objective was to evaluate if the half dose would be as effective as the full dose in reducing moderate and severe cases of the disease. Through this database, it is possible to analyze and assess the effectiveness of administering the ChAdOx1 nCoV-19 vaccine in half doses, as well as comparing it to the use of full doses. This information can be used by researchers, healthcare professionals, and authorities responsible for vaccination policies to support decisions and recommendations related to COVID-19 immunization.
