       | unsafe still it should still be reduced and eliminated to make it
       | not unsafe like that. I do not know how to fix, other than
       | possibly to reduce adding more PFAS, but maybe there is some. I

             | Can you explain this thinking? What you've said so far
             | sounds like an argument from incredulity, not backed up by
             | anything.
             | 
             | Radon testing is fairly straight-forward, the nuclear
             | science behind it is all rigorous and well understood;
             | radon gas decays into radioactive "radon daughters" that,
             | not being gases, settle as dust in places where there is
             | poor airflow. You can test for radon in a building by
             | either sampling the air in the building, or by leaving a
             | filter there for a while and then testing the filter for
             | radon's daughters. If you do this testing, you find that
             | radon is prevalent in some areas and a non-issue in many
             | others. Do you think this testing was never done, or the
             | results mistaken for some reason?

             | 
             | Maybe you're incredulous because you heard this claim out
             | of context? Smoking is said to be the cause of 80-90% of
             | lung cancers; the "second biggest cause" is just the
             | scraps, under 20%.

               | We don't know that the amounts of radon found in

               | caused are arrived at by starting with something we do
               | have knowledge about - the massive amounts of radon in
               | coal mines and it's effects on miners - and then drawing
               | a straight line on a graph, assuming there's no threshold
               | where radon risk drops to zero, and computing what share
               | of lung cancer deaths would result from that model.

             | I don't necessarily agree with the "corporate death

             | death penalty - that organisations like individuals are not

             | wealth unrelated to the crime.
             | 
             | BUT: It's a good example of _radical_ action that 's needed
             | _right now_ , so that's why I put it out there. The one
             | thing that I vehemently disagree with you about is that

               | They deliver an mRNA sequence into your body. mRNA is a
               | relatively short-lived form of RNA that is transcribed
               | into protein a handful of times before being degraded by
               | endonucleases [1, 2].
               | 
               | As you said, the mRNA in the COVID vaccine encodes the
               | spike protein. When your body's cells encounter it, they
               | produce the spike protein. Every cell in the body
               | presents some of the proteins that it creates on its cell
               | surface in a structure called the major
               | histocompatibility complex I (MHC I). This is the body's
               | built in QA system: immune cells scan these proteins to
               | check if any of your cells have been infected with a
               | virus and are producing viral proteins [3].
               | 
               | When your body's white blood cells encounter spike
               | proteins on the MHC I, an immune response is triggered
               | [3]. This is a very long series of cascading steps, but
               | the important part for us is that it leads to the
               | creation of memory B cells, which are long lived cells
               | that produce antibodies to the offending viral protein
               | [4].
               | 
               | While your body is mounting this response, you develop a
               | fever. Usually 24 - 48 hours after the vaccination. A
               | fever is a sign that your immune system is revving up. As
               | the mRNA degrades and the spike protein is cleared out,
               | the immune system winds back down and the fever
               | dissipates.
               | 
               | But the memory B cells stick around. The next time your
               | body encounters the spike protein, the antibodies
               | produced by memory B cells latch onto the protein and
               | start a chemical reaction that triggers a fast-tracked
               | immune response.

               | No, it is not. The production is only transient. mRNA is
               | a very short lived substance. (See my explanation above.)
               | 
               | It's easy to prove: If you _did_ still have spike
               | protein, you would continue to have fevers. Fever =
               | fulminant immune response [5]. As I said earlier, that 's
               | the entire point of a vaccination: to kick start the
               | immune response if even a small amount of the spike
               | protein is detected and reduce the lag time in which the
               | virus could continue to invade cells in your body while
               | your immune system is still revving up [6].

               | 
               | RNA vaccines are actually an amazing jump forward in
               | vaccine technology, on the level of the jump from vacuum
               | tubes to transistors in computers [7, 8].
               | 
               | Before RNA vaccines, every vaccine was a bespoke
               | creation. You had to study the virus, find a way to alter
               | its genes so that it's either dead (called an inactivated
               | form) or too weak to cause a serious infection (called an
               | attenuated form), but also still similar enough to the
               | original virus to elicit the same immune response (cross-
               | immunogenicity).
               | 
               | There weren't any good modeling tools for this. It was
               | total trial and error. You had to create the virus, test
               | it on an in vitro or live (i.e. animal) model and see
               | what happened. The iteration time was very slow.
               | 
               | RNA vaccines are a game changer:
               | 
               | 1. They allow you to isolate concerns: You can deliver
               | just a chunk of the virus and not the whole thing. No
               | more fiddling around trying to hit the balance between
               | attenuation and cross-immunogenicity because you don't
               | have to care about the biology of the overall virus and
               | how all its components interact [7, 8].
               | 
               | 2. They are reprogrammable: You can deliver any RNA
               | sequence you want and thereby manufacture virtually any
               | viral protein you want. If the virus mutates, you can
               | alter the RNA sequence in the vaccine to match without
               | having to rebuild the vaccine from step one [7, 8].
               | 
               | 3. They are easily mass produced: It's a lot easier to
               | replicate RNA by PCR than it is to culture a virus [9].
               | 
               | This has big ramifications for turn-around times for
               | developing a new vaccine or refining an existing one. It
               | is honestly a blessing that the technology matured now,
               | as we become increasingly global. It may end up being
               | essential if the next pandemic involves a virus with
               | lethality on the order of smallpox.
               | 
               | > I would appreciate links to literature clarifying them
               | 
               | Most of this is covered in Bio 101 or Immunology 101

           | Here is my comment:
           | 
           | This is actually very poor statistics. Take a look at the
           | actual study:
           | 
           | https://www.jhep-
           | reports.eu/article/S2589-5559(22)00122-7/fu...
           | 
           | And look at table 3. They are testing 6 different types of
           | PFAS, and only 1 is statistically significant. They need to
           | be using the Bonferroni Correction because they are checking
           | multiple hypothesis. To do that, you divide the required
           | p-value (0.05) by the number of tests (6). If you do the
           | Bonferroni Correction, none of the PFAS is statistically
           | significant.
           | 
           | Relevant XKCD: https://xkcd.com/882/
           | 
           | Thus the real conclusion is that the study did not find any
           | statistically significant link between 'forever chemicals'
           | and liver cancer.

             | In the text they mention an FDR correction. In which case
             | you typically don't use 0.05 as the threshold. Bonferroni
             | isn't the only way to do that correction, but it a valid
             | method (depending on the pvalue distribution). But with
             | only 6 tests, it's not really that critical. I usually only
             | think of multiple testing correction in the context of
             | thousands of tests.
             | 
             | Given your comment I was expecting something like 5
             | patients per group. But they had 50 cases and 50 controls.
             | In this context, an uncorrected pvalue of 0.02 is pretty
             | solid.

         | 
         | But, by all means, continue to avoid a rational, cautious mode
