    To me the primary concern is that the ratio of vaccinated:unvaccinated cases is very separate from the probability of catching the disease when exposed. With a highly vaccinated population, it is quite likely that 50% of cases will be among the vaccinated.

    • @MichaelTanMusic
      @MichaelTanMusic  3 года назад +4

      Even higher, i would suspect... hypothetically 100% in a completely-vaccinated population.
      And i agree, the probability of infection given exposure is a very important factor to consider when describing vaccine effectiveness.

      But when you plug that number (vaccinated deaths) into the whole population, it gives the impression that the rate is relatively higher than it is.

    • @MichaelTanMusic
      @MichaelTanMusic  3 года назад +3

      @@sarqf212 Oh, I think i've misunderstood your question. Are you saying that the compound statistics for all deaths is misleading, because it's mostly old people who die? This is only misleading in the context of claiming that a 5% chance of death applies equally to people of all ages, which I think is easy to explain as not the case. That is, when I say a disease has an average 5% mortality, most people will not simply assume that a healthy 20 year old is at equal risk as a 70 year old with health issues.
      This video is specifically looking at whether the effectiveness of VACCINATION can be born out by looking at the compound data.

    Very interesting. People these days are not yet educated enough in a general sense to be able to understand statistics properly. That's why it's so easy to mislead the public with sensationalist but false headlines. And as long as this is allowed to remain profitable, people are gonna get hurt because of it.

    The timing of the video is the factor that made me write this.
    If it hadn't been done during this pandemic then I'd agree with it, because it clearly summarizes your point.
    The over simplification occurs due to the fact that the word "vaccine" in the video will make the viewer think all vaccines are the same.
    This just isn't true, live and killed virus vaccines are far more effective in the real world than say vector vaccines. Also the maker of the same type of vaccine can give very different results, eg: Russia vs China.
    There are different strategies for different vaccines. Some vaccines try to stop the spread (HPV vaccine), others prevent severe illness and death (small pox vaccine)
    The general health of the population is a big factor. Currently the West has 60% of its population with unhealthy BMI(60%). The healthy(40%) are a minority. Health plays a major factor in how the immune system responds to a virus.
    And today, politics, the media and money determine what is and isn't a good vaccine and what is and isn't a good strategy. Eg: New Zealand vs the UK.
    I guess if you hadn't used vaccines as an example it wouldn't have bugged me.
    Oh well, my fault.

    • @Jacquobite
      @Jacquobite 2 года назад +4

      He said the people in the example "had been vaccinated against the disease". At no point did he mention which disease and if there is more than one vaccine for it. The fact that you latched onto this show pretty clearly what you are like.

    • @peterjames37
      @peterjames37 2 года назад

      @@Jacquobite hahaha, the irony of your statement also tells us what type of person you are.
      My point is still very valid. This is because viruses affect different people differently. Using vaccinations as an example for Simpson's Paradox is an over simplification of vaccines and their effect on people. Eg: Covid, the WHO states that 90 to 99% of people are naturally immune to the virus. Therefore, regardless of whether a vaccine is used or not, 90 to 99% of people won't suffer from it because they are naturally immune, and the death rate is even smaller. You need to prove that it is the vaccine that is preventing the death and suffering and not the natural immune system that is preventing the death and suffering first. This FACT is not being taken into account in the video. Does the example explain Simpson's Paradox? YES, is it a realistic example of vaccination? NO.

    I don't get it. Let's say for simplicity 100 people died, 55 were vaccinated and 45 were unvaccinated. We need to split these 100 people in 3 groups, so that in each and every group the unvaccinated are more than the vaccinated, and I don't think this is possible! Can anyone find such a combo? Either I or the video missed a critical piece of information!

    • @MichaelTanMusic
      @MichaelTanMusic  3 года назад +4

      Thank you for the comment. If I had 5 minutes, I would elaborate more :) The numbers in these graphs do all add up, and your example is completely plausible. It's very counter-intuitive, and even the simplest example ends up with a lot of numbers!
      I think the thing you are missing is that, when the unvaccinated deaths are shown to be higher than the vaccinated deaths (in each of the age groups at 0:33), we are looking at a PERCENTAGE within each group. It doesn't necessarily mean that *more* unvaccinated people died; in fact, more OLD VACCINATED people died than any other group.
      OK, here's a scenario similar to yours! (It's tricky to reverse-engineer your numbers, but these are similar).
      Let's start with the 60+ group; and say that 58 deaths were in vaccinated people, 34 were in unvaccinated.
      And let's say this corresponds to 12.5% of those vaccinated, and 25% of those unvaccinated; creating a vaccinated pool of 464 people, and an unvaccinated pool of 136. And puts 600 people in this age group.
      In the middle group, say it's 8 and 9 deaths (vax, unvax) corresponding to 2% and 4%. 625 people in the age group.
      And the youngest group, say it's 1 and 4 deaths corresponding to 0.5% and 1% of each group. 600 in this group.
      So, this adds up to 67 vaccinated deaths and 47 unvaccinated deaths. And within each age group, the vaccinated people die less frequently.
      And, add it all up, and the vaccinated deaths are 67/1064 = 6.3%, unvaccinated 47/761 = 6.2%.
      Spooky huh!!
