It's slime-ball who thinks that vaccines are causing negatives health effects and would NOT warn people about them.  Less competition for their own kids, more chance of collecting social security due to the earlier die-off of the chumps, and less people infecting the globe if the de-population death cult is your thing.

A person who bought the 'safe and effective' party line would have no reason to invent 'scare-stories'.  Just the opposite since they earnestly think they will benefit by 'herd immunity'.

Basically, the only people who would provide warnings are people who genuinely thinks there might be real issues and who have an decency instinct to look out for their fellow man.

I suppose there could be a mix here, and that I might be in that category.  People who are gullible enough to eat up the corp/gov/nwo vaccine propaganda will suffer injury to themselves and their progeny and thus be selected against over time.  This could contribute to the strength of our society.  Such people (e.g., modern 'progressives') are causing serious problems at the present time and we could do with fewer of them.  It's an honor and a duty to give those who should not be final-solution'd a chance to hear the other side and wise up though, else Darwinism can't work properly here.

As for the 'Muslim males', I doubt it.  Their task is to break down Western society which has been softened up by a variety of de-masculation programs over the years (including but not limited to vaccination regimes.)  Once that is mostly accomplished the leadership can go ahead and "Kill them.  Kill them both." to borrow a line from Raiders of the Lost Ark.

Mercury is not used as an adjuvant.  It's uses as a preservative.  Most vaccines nowadays contain only a little left over from the manufacturing process, but multi-dose flu vaccines still use it as a preservatives and most of those who are stupid enough to take the flu vaccination get a healthy dose.

Funny thing about mercury:  A hundred years ago someone thought to wonder if it was safe.  To test it, they injected mercury into 12 people (iirc) who were dying of encephalitis.  They all died of encephalitis thus proving that mercury is safe.  And so it stood for most of a century.  Eventually (after a legislator's own grand-kid was damaged) it was taken out of most vaccines, but NOT because it caused any problems mind you.  Just to make 'uneducated' people feel better.

Aluminum is the most common adjuvant at the present.  Vaccines which are problematic to get working contain more of it.  HPV is a good example of this.

Crushed glass as an adjuvant was tried in horses.  Turns out that it cause enough discomfort to the animal to have a bunch of crushed glass in their tissue that it was abandoned.

Another potential adjuvant is squalene which is an oil related to that which lubricates our joints.  It was found through experiments on ignorant and powerless army recruits (like me) that it might be causing joint problems and was a common complaint from those suffering from 'gulf war syndrome.'  I personally got a fuck-load of shots during gulf war and my joints are fine.  Either I am lucky and not prone to problems, or I lucked out and got in a control group.  Impossible to know about such things.  Anyway, I found it interesting that this year only injected flu vaccine is recommended and they are back to using squalene as an adjuvant for older victims.
