No it isn't. The burden of proof is absolutely on the maker of the drug demanding it be injected into every single child in the US or world.
And they have *not* done that. To the contrary, they have spent decades doing everything they can to avoid highly specific and robust data on it. That alone should be a horribly bright red flag.
Again, feel free to take all the time you like, and find me a clinical trial, placebo controlled, that studies the side effects of aluminum hydroxide or the other adjuvants. Just go find one.
The burden of proof is *always* on the person who demands intervention and makes the *explicit* claim that it is perfectly safe.
