Simple but strong evidence of the BCG Tokyo strain efficacy against COVID-19

I have heard so many arguments that there are many more factors that affect the country/region difference such as virus mutations, arrival timing, genes, masks, hygiene, voice language, food spices, etc. I totally agree that there could be many more factors. 

 Here is simple but strong evidence of the BCG Tokyo strain efficacy against COVID-19.

 One Japanese died of COVID-19 in the U.S at the end of April. It is the first COVID-19 Japanese death in the U.S. Let me calculate and summarize the deaths per 1 million population.

 Deaths per 1M at the end of April.
  • The U.S.: around 200
  • Asian American: 110
  • Japanese in the U.S.: around 2
  • Japan: 3
1) The death rate in Japan/ese is one-hundredths of the U.S., less than half of the flu.

 2) There should be other biological reasons other than genes. My hypothesis is that BCG vaccination is the key reason.

 The BCG Tokyo strain may work as ready-to-use vaccination against COVID-19. 
If an adult has BCC vaccinated before, the Mantoux test can work as a second-best solution to resensitize his/her immune memory. This is good because we can keep the necessary BCG vaccine for infants if seniors can use the Mantoux test. 

 I wonder why only a few researchers work on this hypothesis. I have heard that pharmaceutical companies are not interested in the BCG vaccine because it is a very low margin product. I believe all the governments look into this hypothesis.

    Well, I guess masks were a low profit product as well before Covid-19.

(COMMENTS reached the max) If I were North American/West European/Australian, I would take BCG vaccination now against the novel coronavirus pandemic.

I am not a medical expert and this is just a hypothesis; taking BCG vaccination may strengthen immune to the novel coronavirus. If I were American/West European/Australian, I would take BCG vaccination now. Six reasons follow. I declare that there is no conflict of interest for BCG vaccination but I have a big interest in stopping this pandemic.

There have come many comments on the previous post and new comments don't seem to get published anymore. From the initial, some of the comments didn't get published properly. I guess Google is not working on this Blogger seriously. Please leave your comments/inputs here regarding the BCG hypothesis, the correlation between COVID-19 and BCG vaccination. Please be aware that the Blogger comment system seems buggy and some comments don't get published. I try to check the incoming comments and post the comments if I notice they are not published, but I'm not perfect and my time is limited on this.

The largest side effect of COVID vaccine is to accelerate the COVID-19 pandemic in a short-term (This is not a joke, I am serious)

People all over the world were excited to see the NEJM paper on Israel's mass vaccination result and I was one of them (though I think the BCG Tokyo 172 strain vaccine is safer and more effective). BNT162b2 mRNA Covid-19 Vaccine in a Nationwide Mass Vaccination Setting https://www.nejm.org/doi/10.1056/NEJMoa2101765    Estimated vaccine effectiveness for the study outcomes at days 14 through 20 after the first dose and at 7 or more days after the second dose was as follows: for documented infection, 46% (95% confidence interval [CI], 40 to 51) and 92% (95% CI, 88 to 95); for symptomatic Covid-19, 57% (95% CI, 50 to 63) and 94% (95% CI, 87 to 98); for hospitalization, 74% (95% CI, 56 to 86) and 87% (95% CI, 55 to 100); and for severe disease, 62% (95% CI, 39 to 80) and 92% (95% CI, 75 to 100), respectively. Estimated effectiveness in preventing death from Covid-19 was 72% (95% CI, 19 to 100) for days 14 through 20 after the first dose. In short, this paper claims the vaccination effi
