        Probably not, but exposure is cumulative.

        Modern vaccines with mercury used in the 3rd world are not considered to be a high dose.

        The multi-dose versions of some trivalent and quadrivalent influenza vaccines can contain up to 25 micrograms of mercury per dose from thiomersal.

        50 micrograms/litre of blood is considered dangerous.

        But the point being examined here is perception. Not actual danger.

          cumulative

          hmmm https://www.cdc.gov/vaccinesafety/concerns/thimerosal/

          Thimerosal does not stay in the body a long time so it does not build up and reach harmful levels. When thimerosal enters the body, it breaks down to ethylmercury and thiosalicylate, which are readily eliminated.

          and

          Influenza (flu) vaccines are currently available in both thimerosal-containing (for multi-dose vaccine vials) and thimerosal-free versions.

          the point

          how much is needed to cause autism?

          The point is to not be half-ass your way to middle ground fallacies. When you promote this muddying of water, you’re doing their work.

            how much is needed to cause autism?

            Mercury has been identified as a risk factor. There is no Xmg=autism answer.

            This risk was recognised because Thimerosal is no longer used in USA and EU.

            I’m not muddying anything. I’m showing where the original fear stems from. I can state clearly that there is no need to have autism fears with modern vaccines.

              The original fears are much more complex than that. Fear isn’t a pharmaceutical thing that you can read a paper about.

                On the broader topic of fear and medicine, yes.

                But specifically the fear of autism being caused by vaccines is (probably unjustly) centred on Thimerosal.

                  Fear is the reflection of ignorance, and the ignorant don’t read the facts. When you’re basing your hypothesis of influence on the notion that these people know facts, you’re being overly (erroneously) generous.

                  First comes the fear of vaccines, then comes the pseudoscientific justification.

                  Fear of autism is in the same realm as fear of queerness. It’s the same hateful assholes trying to pathologize human non-average human behavior, trying to blame conspiracies, trying to “deconvert” the victims of said conspiracies.

                  And anti-vaccine history is as old as vaccines, and it’s the same assholes. https://www.nature.com/articles/d41586-020-02671-0

                    Fear is the reflection of ignorance

                    Well, no. I’m fearful of parachute jumps. I know they are 99% safe.

                    When you’re basing your hypothesis of influence on the notion that these people know facts, you’re being overly (erroneously) generous.

                    Yes. No-one need know anything about Thimerosal. The only reason it has reached the public consciousness is because of fearmongers.

                    Fear of autism is in the same realm as fear of queerness.

                    There is an element of environmental influence in autism (risk factors linked to various chemicals) that doesn’t exist in sexuality.

                    The Venn diagram may overlap but I don’t think they are the same. There is lots of left wing distrust of anything big pharma related, and things like the Tuskegee experiment didn’t help.
