By Bhavana KunkalikarSep 28 2022Reviewed by Danielle Ellis, B.Sc. In a recent study posted to the medRxiv* preprint server, researchers assessed the effect of severe acute respiratory syndrome coronavirus 2 vaccination in the US.
The team combined a data assimilation technique with a metapopulation model coupled with a Susceptible-Exposed-Infected-Recovered structure. Here, the spread of SARS-CoV-2 throughout and among the 3142 American counties was simulated. The reported case counts for each American county from the time the first COVID-19 cases were discovered there in February 2020 through the date of the first authorized SARS-CoV-2 vaccination on December 14th, 2020, were assessed using the model-inference system.
Related StoriesThe team used data from the US-based Premier Healthcare COVID-19 claims database to multiply the distribution of estimated COVID-19-related hospitalizations prevented by the distribution of expenses per hospitalization episode. The baseline model predicted a total of 16.1 million COVID-19 cases, 1.4 million related hospitalizations, and over 246 thousand deaths between December 14th and June 3rd, 2021. Almost 51% of Americans had received a minimum of one COVID-19 vaccine dose by June 4th, 2021. Location-specific vaccination rates varied greatly, from 35% in Mississippi to 74% in Vermont.
