That seems to be disputed too, this is an interesting read: Increases in COVID-19 are unrelated to levels of vaccination across 68 countries and 2947 counties in the United States.[0] > 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 > 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. > There also appears to be no significant signaling of COVID-19 cases decreasing with higher percentages of population fully vaccinated Of course that could be different for third world countries.

That article is garbage, full of randomly picked data points, not accounting for other variables, blatant misinterpretations and convenient omissions. Anti-vaxxers love posting it.

  Can you elaborate more on that? Legitimate question, I came across this a couple days ago on some other thread here on HN.

    Can you think of some issues with this study? legitimate question. Looking at one data point here. Israel. The data point pretty much represents the peak of the wave caused by the Delta variant. The story in Israel goes that the vaccines worked so well against the previous variants that the entire country went back to normal. But with 60% of the population vaccinated and Delta the effective R number is easily over 1 when there's no other measures in place. Once Israel introduced some new measures (and booster shots), most of the measures are around limits to not-vaccinated people btw, their case rate went down by a factor of 20! So what does this tell us about vaccines, covid, and this "study"?

        Right (also "in part because the vaccination of children takes time to come into effect"). They are hovering around R=1 with very minimal restrictions and still a significant amount of people that won't take the vaccine ("citing the fact that a third of the population remains unprotected. This refers to 670,000 unvaccinated Israelis, more than a million people who haven’t received the booster, and children under 12"). They're making up for the vaccine coverage to some extent by: 1. Lots of people got sick. Israel has a young population and a very strong healthcare system so they were able to manage a very high daily case rate per capita. 2. Booster shots. 3. And now, vaccinating children. I don't think anyone knows yet exactly what sort of waning effect you have after the third booster. It's also hard to say what portion of the change is behavioral changes vs. the vaccine's wane. Now the new variant completely changes the calculus yet again.

      I can think of many actually, but this is not my field of expertise so I don't want to jump on erroneous conclusions and I want to pay close attention to what I say, other than get feedback from others that for sure know a lot more than me. Just to get things straight, I am in no way saying that vaccines are not effective, there is strong evidence that indicates the contrary. I was responding to a user who claimed that the more covid goes around, the more it mutates, and as far as I understand it's what viruses do and therefore is a correct statement. I then linked this study and cautiously pointed out that it is "disputed", which may still be the wrong term in that case or I was erroneously giving too much credit to the paper itself. You then point out that the study highlights the Delta variant peak when dealing with the Israel data, and I could agree on that. What the study is trying to highlight, as far as I can tell, is not to undervalue *vaccination which has strong evidence ww to greatly lower hospitalisation and death risk from covid infection*, but it instead tries to tell that even in vastly vaccinated communities there are a lot of cases and they can't be distinguished from those in communities with lower vaccination rate. So my argument was: if cases are rising in largely vaccinated communities, the virus will inevitably mutate in those communities too and it is not a pattern only related to third world countries with low vaccination rates.

    And that's how this stuff keeps spreading. People who don't really understand what they are passing on passing it on as though it means something to them. If you didn't really understand it, why did you pass it on?

  The authors haven’t done any questionable transforms of the dataset - its literally the whitehouse dataset as a scatterplot. How is it garbage ?

    You can’t compare developing countries that barely test anyone with Portugal which has strong and robust testing. Likely that tons of infections get untested so to prove that vaccine don’t work just because some other country with lower vaccination has less cases makes absolutely no sense. Any epidemiologist knows that and this is why this garbage analysis. What you do is that you compare within the same country where conditions are similar. It’s the same everywhere, virus spread more and leads to more deaths and hospital cases among the unvaccinated.

Maybe countries with fewer vaccines also don't test as often?
