This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
BackgroundCOVID-19 found the world in a state of unpreparedness. While research efforts to develop a vaccine are on-going, others have suggested the use of available vaccines to boost innate immunity. ObjectiveWe analysed three databases UNICEF Immunization Coverage, Worldometer Corona Virus Updates and World Bank List of Economies to establish the association, if any, between vaccination for various diseases and COVID-19 death rates and recoveries across world economies. ResultsMean percentage death rates were lower in countries that vaccinated for Hepatitis-B birth dose (2.53% vs 3.79%, p = 0.001), Bacille Calmette-Guerin Vaccine (2.93% vs 5.10%, p = 0.025) and Inactivated Polio Vaccine 1st dose (2.8% vs 4.01%, p = 0.022) than those which did not report vaccination. In high income countries, a significant negative correlation with death rates was observed with vaccination for Measles-containing vaccine 2nd dose (r = -0.290, p = 0.032), Rubella-containing vaccine 1st dose (r = -0.325, p = 0.015), Hepatitis B 3rd dose (r = -0.562, p = 3.3 x10-5), Inactivated Polio vaccine 1st dose (r = -0.720, p = 0.008). Inactivated Polio Vaccine 1st dose and Measles-containing vaccine 2nd dose also correlated with better recoveries. In Low Income countries, only Rubella-containing vaccine correlated with lower deaths while Yellow fever vaccine was associated with poorer recoveries. ConclusionOur analysis corroborates the potential benefit of vaccination and warrant further research to explore the rationale for repurposing other vaccines to fight COVID-19.
