In this section I address the third round of arguments by Kirsch: https://kirschsubstack.com/p/the-latest-round-in-the-2m-debate.
Kirsch wrote: "CDC state and county case data: x-axis=vax rate. y-axis=relative # of cases to baseline. Regression shows >1.5X higher cases in 2021, and >2X higher cases in 2022. 95% confidence slope increased in both years over baseline in BOTH all state and all county data. This is dispositive as there is nothing that is more fundamental than this data to resolve the question of cases. More vaccines→ more cases in both years."
He linked to a spreadsheet with these plots (where for some reason on the left he claimed that he got high r2 values even though the values were below 0.1):
At first I thought the plots on the left showed the difference in raw number of cases and not cases in capita, which would have been confounded by population size. However actually the plots on the left do correctly show the difference in cases per capita.
However one bias in Kirsch's analysis is that states with a higher percentage of vaccinated people also tend to have more tests performed per capita. But in states with a low percentage of vaccinated people, there tends to also be a lower number of tests performed per capita which probably makes it less likely that COVID infections are detected as cases:

My correlation between the percentage of vaccinated people in 2021 and tests per capita in 2021 was about 0.61:
>a[, cor( vax/ pop, tests/ pop)] [ 1] 0. 61051
But my correlation between the percentage of vaccinated people in 2021 and the proportion of positive tests in 2021 was about -0.60:
>a[, cor( vax/ pop, positive/ tests)] [ 1] -0. 59976
So since the two previous correlations partially cancel each other out, my correlation between the percentage of vaccinated people in 2021 and positive tests per capita in 2021 was fairly close to zero (where positive tests per capita is similar to the metric of COVID cases per capita that was used by Kirsch):
>a[, cor( positive/ pop, vax/ pop)] [ 1] 0. 20839
Kirsch wrote: "New Japan study shows more vaccines→more cases as well: 'The odds of contracting COVID-19 increased with the number of vaccine doses: one to two doses (OR: 1.63, 95% CI: 1.08-2.46, p = 0.020), three to four doses (OR: 2.04, 95% CI: 1.35-3.08, p = 0.001), and five to seven doses (OR: 2.21, 95% CI: 1.07-4.56, p = 0.033).' This is consistent with Table 2 in the CC study."
The Japanese study was a survey with only 931 people who responded. Whether the subjects had contracted COVID or not was determined by a self-reported response to the survey.
The percentage of people who reported that they had contracted COVID
was about 42% among unvaccinated people (211/(211+293)) and
about 54% among vaccinated people (222/(222+187)). However
the study didn't differentiate whether people contracted COVID before or
after they were vaccinated, and some vaccinated people might have
contracted COVID before they were vaccinated.
The survey is supposed to have been administered in December 2023, so it's unusual that only 45% of the respondents reported being vaccinated (409 out of 913).
The odds ratios in the study were not adjusted for testing behavior, and part of the reason why unvaccinated people had lower self-reported occurrence of COVID might be if unvaccinated people were less likely to get tested. The authors wrote they collected the following characteristics, which did not include the number of tests performed or whether people had ever been tested or not: "The questionnaire collected information on demographic characteristics (age and gender), COVID-19 infection status, vaccination status (including the number of vaccine doses received), health status before January 2020 (presence of any chronic health conditions), and various preventive behaviors. Preventive behaviors assessed included regular gargling, mask-wearing, bathing frequency, avoiding crowded places, room ventilation, eating habits, sleep patterns, exercise habits, and maintaining humidity in living spaces."
The Japanese paper was published at Cureus which allows readers to
post comments about the paper. Someone called Sadao Suzuki posted the
following comment:
[https://
First, although the title of the study contains "Case-Control Study," this is not a case-control study. 'The case-control study starts with a group of cases, which are the individuals who have the outcome of interest. The researcher then tries to construct a second group of individuals called the controls, who are similar to the case individuals but do not have the outcome of interest' [1]. In this study, however, the researcher first collects whole study subjects and then divides them into two groups: one with outcome and one without outcome. In this respect, the retrospective cohort approach, which divides the entire subject population by exposure, and examines outcome status by exposure group, is more natural and straightforward. Because the authors chose the framework of a case-control study, Table 1 is divided by outcome information, and an important information of the distribution of potential confounders by exposure status is not known.
Second, the primary outcome of this study was the presence or absence of self-reported COVID-19 infection. However, the time frame of the outcome was not questioned and a longitudinal analysis could not be performed. If a subject was infected with COVID-19 before the first vaccination and then received six additional vaccinations and prevented the infection, then vaccination cannot be the cause of COVID-19 infection. In the study, however, the association would be observed between the vaccination and the infection. Without knowing the time frame of the outcome, a causal relationship cannot be discussed.
Third, the study is inadequate in describing important information. Most importantly, all of the subjects were Yamato project participants and/or employees of SMEs, whose attributes were not described at all. Moreover, the actual questionnaire used is not shown, and the specifics of the questions are not clear. For example, we do not know what "eating habits" refers to. Throughout this paper, such descriptions are severely lacking. In addition, the data set is not publicly available.
Fourth, the studies were derived from two different populations, but were combined without assumption. Here, we would like to point out the possibility of confounding due to the different backgrounds of the two groups, Yamato project participants and employees of SMEs. Confounding could occur if the vaccination or infection status of the two groups differs. Adjustment for the groups or confirmation of the absence of confounding is essential.
Fifth, the study population was described by the authors as "the study team believed that the participants reasonably approximated the broader workforce of SMEs in Japan". However, 504 of the 913 subjects (55.2%) were unvaccinated. Considering that the proportion of unvaccinated persons aged 20 years or older in Japan is 11.6% [2] (as of April 1, 2023), this is a biased population with approximately five times as many unvaccinated persons and is not representative. In this paramount matter, the "reasonable approximation" is completely false. The authors are accountable for the type of population which they chose, why the unvaccinated rate is so high, and with what intent the "reasonable approximation" statement was made.
And last but not least, the validity of the odds ratios is not fully considered. For the odds ratio to be valid, the accuracy of COVID-19 diagnosis must be constant regardless of vaccination status. However, it is conceivable that vaccination is associated with diagnostic diligence for the disease in question, in which case there would be a difference in diagnostic accuracy, resulting in information bias. This bias increases the odds ratio without causality.

A reply to the comment which essentially acknowledged all the errors was posted by Eiji Nakatani who was the first author of the paper. He wrote: "Because our study could not establish whether vaccination preceded infection, causal inference is severely limited. The observed association - more frequent infection reports among vaccinated participants - should not be taken as causal proof of vaccine ineffectiveness or harmful effects. Rather, it points to the need for further exploration, including detailed temporal data and longitudinal designs." He also wrote: "The proportion of unvaccinated individuals in our sample was higher than national averages, indicating possible selection bias and limited generalizability. In retrospect, describing our sample as a 'reasonable approximation' of the broader workforce was inaccurate. We will acknowledge these biases explicitly and refrain from overstating the representativeness of our sample." And he wrote: "Relying on self-reported infections introduces the possibility of information bias. Vaccinated individuals may be more proactive in seeking testing or reporting infections, potentially inflating observed odds ratios."
The response by Eiji Nakatani looks like it was AI-generated:
One comment said that "a GPTZero scan of this document show 100% probability of being AI generated", but comically the first author Eiji Nakatani replied that "the discussion of the potential for AI generation is one interesting aspect regarding this study":
Reference 1 of the Japanese paper says: "Welcome
to the Sprinklr DEV portal. (2024). Accessed: October 16, 2024:
http://dev.sprinklr.com/." But reference 1 doesn't seem to have
anything to do with the sentence it was placed after: "Vaccination campaigns have played a pivotal role in
controlling the spread of severe acute respiratory syndrome coronavirus
2 (SARS-CoV-2) and reducing the severity of COVID-19 [1,2]."
Apparently Sprinklr is an AI customer support service which also
supports generating various types of documents with AI:
[https://
Sprinklr also supports using AI to automatically post replies on social media, so I wonder if the replies by Eiji Nakatani were also automated by Sprinklr or another similar service? It wouldn't have made sense for a real person to write "the discussion of the potential for AI generation is one interesting aspect regarding this study". But on the other hand it seems like a fairly niche task to automate posting replies to a comment section in a scientific journal, and setting up automated replies might take more time than simply posting replies manually. So perhaps a more likely scenario would be that Eiji Nakatani generated the reply with AI but he sent it manually, and he was so poor at English that he didn't understand the reply properly or he didn't bother editing the reply manually.
The last author of the Japanese paper was the alt media celebrity
Masanori Fukushima. A video from a press conference where he discussed
the paper was widely shared on social media, and a version of the video
with English subtitles was posted by Aussie17:

Aussie17 frequently posts subtitled videos produced by the
astroturfed anti-vaccine movement in Japan and other Asian countries.
His videos are often reposted by bots that promote Miles Guo and other
bots that promote content from the fake alternative media. In 2024 I
scraped the reposts of about 80 accounts I suspected to be bots that
promoted content from controlled alternative media, and I counted how
many times they reposted different COVID-related accounts relative the
number of followers of each account, but Aussie17 ranked 8th highest.

Kirsch wrote: "CDC/NIH study: The ONLY statistically significant results were: vax increases infection risk, natural infection lowers infection risk. Never in human history does a vax make things risk worse in kids and better in adults. Table 2 confirmed CC findings: prior infection reduces risk; prior vaccination increases risk."
The study was behind a paywall and not at Sci-Hub or Researchgate so I wasn't able to read the study.
However Kirsch didn't mention that the study only included children between the ages of 6 months and 4 years.
In the next plot, the rate of COVID cases per capita was slightly
higher in unvaccinated than vaccinated ages between 6 months and 4
years. But in ages 5-11 the rate was higher in unvaccinated people
during some periods and in vaccinated people during other periods, but
in older age groups the rate was clearly higher in unvaccinated people:
[rootclaim.
Ages 6 months to 4 years have such a low percentage of vaccinated people that children from various vulnerable subgroups might be overrepresented among vaccinated people.
However if you look at the data for ages 0.5-4 in the CDC dataset for
COVID cases and deaths by vaccination status, there's a total of 64
COVID deaths in unvaccinated people but only one death in fully
vaccinated people, even though vaccinated people account for only about
3.2% of total person-weeks:

The CDC dataset excluded partially vaccinated people with one dose or a second dose less than 2 weeks ago, so they are also not included in my code above.
Kirsch wrote: "Harvard (Subramanian (2021) was 68 countries. 90% slope CI was [2.83, 25.02] so we are 90% confident that the vaccine INCREASED infections across 68 different nations in September 2021. Data here."
The paper said: "We used COVID-19 data provided by the Our World in Data for cross-country analysis, available as of September 3, 2021 (Supplementary Table 1) [4]. We included 68 countries that met the following criteria: had second dose vaccine data available; had COVID-19 case data available; had population data available; and the last update of data was within 3 days prior to or on September 3, 2021. For the 7 days preceding September 3, 2021 we computed the COVID-19 cases per 1 million people for each country as well as the percentage of population that is fully vaccinated."
However richer countries have a higher percentage of vaccinated
people than poorer countries, but richer countries also performed more
tests capita which might explain why richer countries had more cases per
capita:
[rootclaim.
Kirsch wrote: "Independent survey of 500 Americans on COVID infections done by third party firm PureProfile: More vaccine doses→ higher risk of infection and number of infections."
He linked to a spreadsheet which seems to have been emailed to him by Leonard Murphy from the PureProfile company. Kirsch said the survey was an "independent survey", but I don't know how independent it in fact was, because a year ago Kirsch commissioned Murphy to produce another similar survey, so the new survey may might also been commissioned and paid by Kirsch. There are currently little details available about the new survey, but Kirsch might eventually publish a Substack post about it.
But anyway, the spreadsheet posted by Kirsch included these columns:
However the survey might suffer from a bias where vaccinated people were more likely to get tested than unvaccinated people. It's not possible to adjust for the bias because there's no column that asked people if they had ever been tested for COVID or how many times they got tested.
There was no data for the date when people got the first dose, so it is also not possible to calculate the number of COVID cases per person-weeks.
Kirsh did a simple analysis based on the survey where he didn't even differentiate between people who got COVID after vaccination or before vaccination:
There were 152 vaccinated people who reported a COVID case, but they included 42 people who reported a case before vaccination and 20 people who reported a case both before and after vaccination:
download.file( " https:// github. com/ skirsch/ covid/ raw/ refs/ heads/ main/ debate/ US% 20infection% 20survey% 20by% 20PureProfile. xlsx", " US infection survey by PureProfile. xlsx") t=setDT( readxl:: read_ excel( " US infection survey by PureProfile. xlsx", sheet=2)) t[, covid: =` Have you EVER tested positive for, and/ or been diagnosed with, COVID- 19?`] t[, time: =` When were you diagnosed with COVID- 19?`] t[,.( vax=` num shots` > 0, time, covid)] t[` num shots` > 0& covid==" Yes",.( people=N), time]| > print( r=F) # time people #After receiving a COVID- #19 vaccination 87 Before receiving a COVID- #19 vaccination 42 Both before and after receiving a COVID- #19 vaccination 20 Unsure 3
There were 107 people who reported a COVID case when they were vaccinated but 109 people who reported a COVID case when they were not vaccinated:
t[`num shots` > 0& time% like% " After| Both" & covid==" Yes",. N] # 107 (vaccinated cases) t[(`num shots` ==0|(` num shots` > 0& time% like% " Before| Both")) & covid==" Yes",. N] # 109 (unvaccinated cases)
About 62% of all people reported being vaccinated:
t[,.(people=. N),.( vaccinated=` num shots` > 1)]| > print( r=F) # vaccinated people #TRUE 312 #FALSE 188
The percentage of vaccinated observation time out of total observation time is of course going to be lower than the percentage of vaccinated people. I didn't find any information when the survey was conducted. If for example the survey was conducted in mid-2021 then the rate of COVID cases per observation time would be higher for vaccinated people, but if the survey was conducted in 2024 then the rate would be higher for unvaccinated people. (Even though observation time during the period with low COVID cases after early 2022 would not be very relevant to determining COVID infection risk, so it might be better to do a time-series analysis that compares cases per person-weeks over time, but that is not possible based on Kirsch's survey because it doesn't show the dates of when people were vaccinated or got COVID.)
However I consider it plausible that the entire survey was fake,
because Kirsch has a history of publishing fake data like the data from
the anonymous military doctor he published in August 2024.
[rootclaim.
Kirsch's spreadsheet for the PureProfile survey indicates that the data was sent to him by someone called Leonard Murphy:
I found that Kirsch is earlier supposed to have hired Murphy to
conduct a poll which surveyed a thousand households that were chosen to
be representative of the American population. But the survey seems fake
because supposedly 194 households reported a death since 2021, and
nearly half of households reported that they thought the death was
caused by a COVID vaccine:
[https://
Kirsch published his post about Leonard Murphy's earlier survey in January 2024, so the survey would have likely included data up to either January 2024 or some point of 2023. However only about 3% of the US population died between 2021 and 2023. And many of the people who died lived in elderly homes, so they were unlikely to be included in a random sample of US households unless the households also included elderly homes (and even in that case each elderly home included would have contributed only one death to the survey). There is also a survivorship bias where if someone died but they were the lone member of their household, then there was no other member of the household left who could have reported the death.
Kirsch wrote: "13,000 person survey: Consistent with CC study: more vaccines→ more cases."
He linked to this poll he did on Substack in January 2025:

One problem with his survey is that he asked people how many times they got COVID since January 2021, but there were probably some people got COVID in January 2021 or later but before they were vaccinated. Someone in the comments said: "I answered but there's an issue that you probably need to fix. I got one shot (J&J), and I've had COVID one time since January 2021. But the issue is that I had COVID BEFORE I had the shot."
Kirsch's unvaccinated followers may have been less likely to get tested than his vaccinated followers. Many of his followers even think that viruses are not real or that PCR tests are fake, so that even if they would've tested positive for COVID, they might still answer that they didn't have COVID.
Kirsch might have asked separate questions for how many times his people think they had COVID, how many times they tested positive for COVID, or how many times they had symptoms of a respiratory illness. And he could've also asked how many times people got tested for COVID to see if there's a bias where unvaccinated people were less likely to get tested than vaccinated people.
One person in the comments wrote: "Actually, I said unvaxxed, zero times, but I DID get a bad cold once that could have been COVID. I NEVER took this screamdemic very seriously, never got tested, would not know COVID from regular cold or flu. There must be many others like me and maybe such a phenomenon is the real explanation for your results." Another person wrote: "Since I have not been tested for COVID, its a bit difficult to say whether I contracted it. I HAVE been ill in this period since 2021, but as far as I can tell, its been influenza/cold (but then again: Whats the real difference?!)" A third person wrote: "I supposedly got COVID once, but I'm not sure I had it. The PCR tests are fraudulent. I was told I had COVID, but who knows? I may have simply had a bad cold." A fourth person wrote: "No one has ever had sars-cov-2 covid19, It doesn't exist !" And a fifth person wrote: "The problem is that its impossible to know what illnesses were/are 'covid' and what were/are just plain ordinary illnesses (or poisonings). I never 'tested' when I was ill. And of course the 'testing' was fraudulent."
Another person in the comments seems to have implied that they tested positive for COVID at one point but they still answered that they didn't get COVID: "I'm taking 'got covid' to mean tested positive on one of those OTC AG kits, while having symptoms. That's how I answered. In truth, I never had 'covid' because I never had any novel symptoms, nor do I accept those test kits as revealing anything real about my health (or anyone else's)."
One commenter pointed out: "I also think the opposite is true that the unvaccinated don't want to admit they had covid or they didn't test for it and so they have no idea if an illness was covid. I'm unvaccinated and I think I had it twice but I can't say for sure because I didn't test for it. I just thought the symptoms were different than your average flu."
Another comment said: "Those polls don't work man, for various obvious reasons such as people not getting vaccine in the first place, due to natural immunity, because of being young and healthy, plus people being tied closer to health care measurements, such as vaccines, receicing also more testing. But of course the biggest flaw here is that people don't actually know how many times they got Covid. Such layman polls only prove that the vast majority of people are incompetent to interpret statistics."
Kirsch posted this plot, where he had added annotations to a plot from the website of the California Department of Public Health:
The caption of the original plot by CDPH says that the plot is
supposed to show cumulative COVID deaths as a percentage of cumulative
cases 30 days earlier:

However I think CDPH might have forgotten to actually shift the cases by 30 days, because the plot by CDPH looks similar to my black line here where I didn't shift the cases and not the red line where I shifted cases forwards by 4 weeks, and in my red line the cumulative CFR actually went down during January and February of 2021:
