Countries with a higher percentage of fully vaccinated people have higher rates of Covid-19 cases, a study by Harvard researchers claims.
The study, titled, “Increases in COVID-19 are unrelated to levels of vaccination across 68 countries and 2,947 counties in the United States,” was published late last month at the National Institutes of Health website and the peer-reviewed European Journal of Epidemiology.
On its face, the study purports rises in Covid cases are unrelated to vaccination rates, however, data presented in the study gives the exact opposite impression.
For example, the study claims, “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 days.”
However, it goes on to say, “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.”
“Notably, Israel with over 60% of their population fully vaccinated had the highest COVID-19 cases per 1 million people in the last 7 days,” the study authors state.
“The lack of a meaningful association between percentage population fully vaccinated and new COVID-19 cases is further exemplified, for instance, by comparison of Iceland and Portugal,” the study notes, going on to demonstrate a meaningful association.
“Both countries have over 75% of their population fully vaccinated and have more COVID-19 cases per 1 million people than countries such as Vietnam and South Africa that have around 10% of their population fully vaccinated.”
The study goes on to illustrate the correlational relationship between vaccines and Covid rates in US counties.
“Across the US counties too, the median new COVID-19 cases per 100,000 people in the last 7 days is largely similar across the categories of percent population fully vaccinated.”
“Of the top 5 counties that have the highest percentage of population fully vaccinated (99.9–84.3%), the US Centers for Disease Control and Prevention (CDC) identifies 4 of them as ‘High’ Transmission counties. Chattahoochee (Georgia), McKinley (New Mexico), and Arecibo (Puerto Rico) counties have above 90% of their population fully vaccinated with all three being classified as ‘High’ transmission.”
“Conversely, of the 57 counties that have been classified as ‘low’ transmission counties by the CDC, 26.3% (15) have percentage of population fully vaccinated below 20%.”
