I was tempted to title this thread "Undeniable proof vaccines don't do jack", but that's not quite the truth as you'll see. In recent times I've seen
quite a few stories about what fraction of people hospitalized have been vaccinated, but looking at hospitalization rates isn't a very useful
indicator. Consider that if 100% of people were vaccinated, then 100% of people hospitalized would be vaccinated. In a place where not many people are
vaccinated, the fraction of unvaccinated people being hospitalized will obviously be higher.
That is one of the main reasons we see so many conflicting narratives when it comes to hospitalization rates of the unvaccinated vs vaccinated. A much
better way to measure the effectiveness of the Covid-19 vaccines is to compare the most vaccinated countries with the least vaccinated, and see if
they have any difference when it comes to stats such as case numbers and death rates. What I decided to do was take the
open source data provided by Our World in Data, and create a scatter chart to
compare all countries.
On the x-axis we have the number of vaccinations per capita, which means how many vaccines each person has received on average. So countries further
to the right have higher vaccination rates. It looks like only one country has fully vaccinated almost every citizen (aka given everyone 2 doses), and
that is the United Arab Emirates, although I haven't looked into how they achieved it or how believable it is. I did exclude a few tiny
islands/countries and a couple of strange outliers such as China because they refuse to report any Covid-19 deaths.
On this first chart, the y-axis has the number of Covid-19 cases per capita, which is just the number of cases over a period of time divided by the
total population size. We can't simply plot the number of cases in each country, because it highly depends on the size of the population. So by using
the cases per capita we get a "normalized" value which allows us to compare all countries on equal footing. I specifically chose to use the August 1st
to September 30th time period because that's when new strains such as Delta started spreading in many countries.
Also, the vaccination rates were lower in the past, so if I use data going back further in time it will make the analysis less reliable. Basically
what I want to do is measure the effectiveness of the vaccine by comparing countries with different vaccination rates, and more specifically I want to
see how effective the vaccines are against the newer strains of Covid-19 which the vaccines were not designed for. If the vaccines are effective, we
should expect to see lower cases per capita in the most vaccinated countries, and the trend should be quite clear.
Maybe I'm seeing things, but it certainly looks like the above chart shows the opposite trend than what would be expected from an effective vaccine.
It actually looks like Covid-19 has an easier time spreading through countries with higher vaccination rates, and those least vaccinated are forming a
cluster of countries with very low case numbers. Well they admit the vaccine wont stop the spread of Covid-19, but maybe it will still reduce the
symptoms? Well lets create another scatter chart, this time analyzing the fraction of cases which result in death.
This trend is more in line with what we would expect to see from an effective vaccine. It appears as though the vaccines will indeed lower your
chances of dying should you contract Covid-19. Lets sum up what we know, the vaccines allow Covid-19 to spread more easily, possibly because it
creates more asymptotic cases, and partly because vaccinated people feel more safe to roam around. However, the vaccines don't appear to be completely
useless even against the strains currently circulating, they do provide some protection. So what is the end result?
The above chart shows us Covid-19 deaths per capita (different to the previous chart which was deaths per case). This is arguably the most important
chart, because it will tell us if the vaccines are actually reducing the number of overall Covid-19 deaths in a given population. It turns out, even
though the vaccines provide some protection, they also increase case numbers, and those two things essentially cancel each other out. That is what we
see in this 3rd chart, it's almost a combination of the trends seen in the first two charts.
We can see the least vaccinated countries have low death rates, but the most vaccinated countries also seem to have fairly low death rates, and the
worst off countries are those in between. It almost looks like a Gaussian distribution, which would be hard to explain if you only looked at this 3rd
chart and not the first two. So based on this analysis, I would have to conclude the vaccines aren't providing any overall benefit. I would also
encourage others to run their own analysis and double-check my results. Here is the legend for the charts:
