Oh yes, I'm not vaccinated. Of course, I'm a scientific person. I always do that. There were many reasons for what I did, but then of course I had to check it out. I wonder if vaccines work and I misunderstood that? Alright. I did a study for this. The sources I refer to in the study are the vaccine map, which is based on official sources by the NYT, and the wordmeter info website, which is a statistics organization.
For highest precision, I took the 25 most populated countries in the world. Ah yes, I think China is manipulating the data and it shouldn't be on the list. They cause a misunderstanding that vaccines work. However, for the sake of being objective, I did not exclude them from the statistics. Then on the second try, I took them out of the statistic and tried it that way.
ABSTRACTVaccination rates and covid related mortality rates by in the world's 25 most populous countries were used as a source in the study. An average vaccination rate and an average death rate for 25 countries were obtained. Countries were marked according to whether they were above or below the average vaccination rate. Countries were also marked according to whether they were above or below the average death rate. If a country has vaccinated more than the average, the confirmation that the vaccine is working is that the average death rate is lower than the world average. Therefore, there should be an inverse relationship between the vaccination rate and the death rate. Therefore, the vaccine has worked in countries where the vaccination rate and death rate differ according to whether they are above or below the average. In countries with the same two values, the vaccine did not work.
The resulting values are:
As we can see, the number of countries where the vaccine works is 11 out of 25 countries. In 14 out of 25 countries, the vaccine did not work or had a statistically adverse effect.
When we look at the population, the vaccine had a positive effect on 46% of the world's population, and the effect was negative on 54%.
SECOND STUDY WITHOUT CHINAIn the second study, it was excluded because the virus leaked in a lab environment and the Chinese data, which was at the center of the conspiracy, may have been manipulated.
ABSTRACTVaccination rates and covid related mortality rates by in the world's 24 most populous countries were used as a source in the study, exluding China. An average vaccination rate and an average death rate for 24 countries were obtained. Countries were marked according to whether they were above or below the average vaccination rate. Countries were also marked according to whether they were above or below the average death rate. If a country has vaccinated more than the average, the confirmation that the vaccine is working is that the average death rate is lower than the world average. Therefore, there should be an inverse relationship between the vaccination rate and the death rate. Therefore, the vaccine has worked in countries where the vaccination rate and death rate differ according to whether they are above or below the average. In countries with the same two values, the vaccine did not work.

The situation of the countries was not affected by the new situation. Again, countries are in same place on whether the vaccine works or not. Since only China was excluded from the statistics, there is a big difference in population now.
While the vaccine worked in 27% of the population of countries, it had an adverse effect in 72%.
Of course, when calculating the median, one can start from the total number instead of the average values of the countries, and in this case the values can vary between 1-3%.
Vaccines are free of charge, you know what it is said; "
cheap meat yields dilute soup".
I think that, in a scientific sense, is unnecessary risk. But of course I cannot interfere with your decision. You can still write the formula I wrote above in a corner of your mind. Oh, I'm coughing today, I think it's time for eucalyptus tea.
