Increases in COVID-19 are unrelated to levels of vaccination across 68 countries and 2947 counties in the United States
"The narrative related to the ongoing surge of new cases in the United States (US) is argued to be driven by areas with low vaccination rates [1]. A similar narrative also has been observed in countries, such as Germany and the United Kingdom"
Findings
"At the country-level, there appears to be no discernable relationship between percentage of population fully vaccinated and new COVID-19 cases"
"There also appears to be no significant signaling of COVID-19 cases decreasing with higher percentages of 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"
"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%."
Interpretation
"The sole reliance on vaccination as a primary strategy to mitigate COVID-19 and its adverse consequences needs to be re-examined"
"the effectiveness of 2 doses of the BNT162b2 (Pfizer-BioNTech) vaccine against preventing COVID-19 infection was reported to be 39% [6], substantially lower than the trial efficacy of 96%"
"In summary, even as efforts should be made to encourage populations to get vaccinated it should be done so with humility and respect. Stigmatizing populations can do more harm than good."
