Vaccination Rates Not Linked to Lower COVID Rates, Epidemiology Paper Finds

A new peer-reviewed study that analyzed 168 countries and 2,947 US counties found that higher vaccination rates were not associated with fewer COVID-19 cases.

At the country-level, there appears to be no discernable relationship between percentage of population fully vaccinated and new COVID-19 cases in the last 7 day," researchers concluded in a paper published in the European Journal of Epidemiology. In fact, the trend line suggests a marginally positive association such that countries with higher percentage of population fully vaccinated have higher COVID-19 cases per 1 million people."
