https://archive.md/tpxhZ#selection-2311.0-2314.0Uh-oh - Increases in COVID‑19 are unrelated to levels of vaccination across 68 countries and 2947 counties in the United States
Scientific study conducted by Harvard and Canadian researchers published in the European Journal of Epidemiology in August 2021.
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.
As the Covid pandemic continues to defy predictions about when it will finally be ‘over,’ there is a curious phenomenon taking place across the United States and around the globe: Covid-19 case rates increasing alongside vaccination rates.
The textbook examples of this disturbing trend are the nations of Israel, the United Kingdom, and the United States. Israel is now experiencing its fourth wave, which is being accompanied by another round of ‘booster shots.’ Israel has 61.5% of all adults “fully vaccinated” (although the use of ‘booster shots’ throws the term into question.)
Notably, Israel with over 60% of their population fullyvaccinated 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.
“Of the top 5 counties that have the highest percentageof population fully vaccinated (99.9–84.3%), the US Centers for Disease Control and Prevention (CDC) identifies 4 of them as ‘High’ Transmission counties.”

So, um Pfizer's stance on boosters:
“Although two doses of the vaccine may still offer protection against severe disease caused by the Omicron strain, it’s clear from these preliminary data that protection is improved with a third dose of our vaccine,” Pfizer’s CEO Albert Bourla said. “Ensuring as many people as possible are fully vaccinated with the first two dose series and a booster remains the best course of action to prevent the spread of COVID-19.”
Seems this published study refutes that claim.
Edit - So it would seem the vaccine remains a great choice for the elderly and those with comorbidities to avoid extreme reactions to COVID. It seems questionable to believe full-scale mandates will result in stopping the spread of COVID.
Edit 2 - authors' conclusion:
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 moreharm than good. Importantly, other non-pharmacologicalprevention efforts (e.g., the importance of basic publichealth hygiene with regards to maintaining safe distance orhandwashing, promoting better frequent and cheaper formsof testing) needs to be renewed in order to strike the bal-ance of learning to live with COVID-19 in the same mannerwe continue to live a 100 years later with various seasonalalterations of the 1918 Influenza virus.
ahem.
You gotta make it sexy! Hips and nips, otherwise I'm not eating.
