Study correlation between COVID vaccination and hospitalisation rates

Abstract

This study aims to obtain more easily understood numbers and figures for the ease of the public in understanding the effectiveness of COVID-19 Vaccines against cases and hospitalisations. Using data from the United States CDC COVID Data Tracker, it was found through the observational analyses that an estimated threshold of 40% vaccination coverage would result in a drastic fall in the 7-day moving average of cases. It was also identified through statistical analysis that increases in vaccination coverage would correspond to a increase in averted COVID-19 cases and hospitalisations. However, much of these values should not be used as a policy target due to their nature as a policy outcome observation, and the exclusion of related variables from the dataset makes it difficult to disentangle the correlated variables to attribute causal relations.
