New paper in European Journal of Epidemiology by researchers from Harvard and Canada:
“𝗜𝗻𝗰𝗿𝗲𝗮𝘀𝗲𝘀 𝗶𝗻 𝗖𝗢𝗩𝗜𝗗𝟭𝟵 𝗮𝗿𝗲 𝘂𝗻𝗿𝗲𝗹𝗮𝘁𝗲𝗱 𝘁𝗼 𝗹𝗲𝘃𝗲𝗹𝘀 𝗼𝗳 𝘃𝗮𝗰𝗰𝗶𝗻𝗮𝘁𝗶𝗼𝗻 across 68 countries and 2947 counties in the United States”
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 (Fig. 1). 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 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. 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.
Hmm.
