Covid-19 vs. BCG Universal Immunization: Statistical Significance in the Early Phase of the Pandemics

A possible correlation between the impact of Covid-19 and universal immunization program against tuberculosis with Bacillus Calmette-Guérin (BCG) vaccine was suggested previously, based on apparent lower epidemics a record national BCG program. In this work time-adjusted dataset statistical data by subnational health jurisdictions at time point six months after local arrival used to perform analysis significance hypothesis milder early phase scenario. With accumulated up analysis, evaluated both qualitatively quantitatively conclusion that it has achieved statistically significant level confidence. The conclusions research can be in development epidemiological policy as well rationale investigate origin mechanisms broad immunity protection associated an early-age exposure vaccine.
