Nature “study” claims Covid vax prevented 354,000 Japanese deaths in summer 2021
Just when I thought I might never have to write about the Covid-19 Pandemic in Japan again, the Nature journal Scientific Reports publishes a hallucinogenically ludicrous counterfactual modelling study co-authored by Hiroshi Nishiura, the Japanese government’s go-to guy for epidemiological modelling madness
I didn’t think Nishiura would ever again produce anything as insane as his 2020 prediction of “420,000 dead without social distancing”…
…but it looks like I underestimated him. Here’s the abstract to the study “Evaluating the COVID-19 vaccination program in Japan, 2021 using the counterfactual reproduction number”.
Japan implemented its nationwide vaccination program against COVID-19 in 2021, immunizing more than one million people (approximately one percent) a day.
However, the direct and indirect impacts of the program at the population level have yet to be fully evaluated. To assess the vaccine effectiveness during the Delta variant (B.1.617.2) epidemic in 2021, we used a renewal process model.
A transmission model was fitted to the confirmed cases from 17 February to 30 November 2021. In the absence of vaccination, the cumulative numbers of infections and deaths during the study period were estimated to be 63.3 million (95 percent confidence interval [CI] 63.2–63.6) and 364,000 (95 percent CI 363–366), respectively;
the actual numbers of infections and deaths were 4.7 million and 10,000, respectively…
We demonstrated the very high effectiveness of COVID-19 vaccination in Japan during 2021, which reduced mortality by more than 97 percent compared with the counterfactual scenario.
Put simply, Nishiura et al. input a load of outlandish assumptions into their model to make it estimate that without the jabs, about 50 percent of the population would’ve been infected and 0.3 percent of the population would’ve died of Covid during the Delta wave alone.
The nicest thing I can say is that they clearly omitted the assumption that Japan’s 100 percent mask rate made a difference.
The authors’ utter unseriousness is evidenced by them including real-world data in the paper that completely refutes the model’s output, such as the below figure from the paper’s supplementary material.
Does it look like the jabs prevented 92.6 percent of possible infections during the Delta wave in summer 2021?
After looking at the above figure, anyone who still regards peer-review as a guarantor of quality might want to consider why neither the authors nor apparently the peer-reviewers bothered to ask the obvious and pertinent question of “Why were cases much lower in the Alpha wave when hardly anyone was jabbed?”
But the paper gets even more delusional. The authors came up with three more counter factual scenarios with even less realistic results.
If the vaccination program had been conducted 14 days earlier than the actual pace, the peak of daily incidence would have decreased by 73 percent, i.e., 98,368 infections (or four times the observed) versus 26,149 (95 percent CI 24,354–27,952) infections in the early schedule scenario.
However, if the program had taken place 14 days later than the actual schedule, the peak of daily incidence would have reached 263,220 (95 percent CI 250,387–276,173) infections, and the maximum daily incidence was estimated to be 33,004 (95 percent CI 30,996–35,258) infections in the elevated coverage scenario [i.e, higher coverage among people aged 10-59].
The ridiculousness of these estimates is evident from just looking at figure plotting them: the early schedule and extended coverage scenarios are almost identical to the Alpha wave before the jabs were made available to the general population, while the late schedule scenario is about 10 times higher.
The reason for publishing this nonsensical drivel becomes clear in the Discussion.
in our elevated coverage scenario (i.e., encouraging more adolescents and people aged 10–59 years to be vaccinated), the total effect was substantial, even when older people were not prioritized for vaccination.
This demonstrates that vaccinating younger individuals with substantial transmission potential is a critical strategy in mitigating the magnitude of the epidemic for an entire population, including children aged < 10 years who were not eligible for the vaccination program.
Basically, by having Nishiura et al. publish a study in a supposedly reputable journal based on a make-believe model that “demonstrates” that jabbing the low-risk young protected the high-risk elderly in summer 2021, future Japanese governments can point to this study to justify pressuring even more members of younger age groups to take warp speed jabs they don’t need during future viral scares.
It also means Fukuoka City will be able to make vax-sceptics want to puke their guts up again with yet another omoiyari wakuchin (vaccination out of consideration) poster.
One other problem with the idea that 50 percent of the country would’ve been infected with Delta if not for the glorious jabs is that most of the population was living under states of emergency and quasi-emergency, as advocated by Nishura.
Is our rotund public health expert finally admitting that closing restaurants early and masking outdoors in 35-degree heat weren’t quite as effective as he and other experts previously claimed? Hardly.
Additionally, a surge in COVID-19 patients observed in July–September 2021 was the largest epidemic wave ever experienced in Japan, and the corresponding period fell under the state of emergency, which was based on a non-legally binding policy in which the government requested voluntary restriction of contacts.
Were PHSM [public health and social measures] not in place under the state of emergency, the number of infections could have been even greater than the observed number.
So the fourth state of emergency might not have looked very effective…
…but without it and the jabs, 70, 80, even 90 percent of the country would’ve been infected!
The pre-determined conclusion of this study can be summed up as follows:
“No matter what the real-world data shows, our model says the vaccines were magical.
The only things we need to do differently next time are rubber stamp the shots’ approval earlier and jab more kids.”
As Covid has dropped out of the headlines, I often wonder if I’ll have anything more to write about.
But as long as Nishiura and his ilk keep pumping out garbage like the above study, I guess I’m going to have to keep at it.

Something that is killing millions is not saving any lives.

Maybe these bogus vaccines were 100% isotonic saline, i.e. 0.9% Sodium Chloride solution.

These clowns and the public seem to think that vaccines (jabs included) work almost immediately. In fact, it’s more like six weeks. This 2 weeks earlier or later idea/prediction/crappy modeling is total BS.
Plus, the delta variant is decidedly weaker, as is each successive variant.
Also, the PCR test remains a crappy test that will detect anything in the cold and flu season as C-19, as it is based on a common nucleic acid sequence from coronaviruses, as admitted by the CDC.
