Alright. And BTW. I retract "weird" bc I don't think nostr:npub1x458tl7h9xcxa66vr4a8pg0h2qz96pnhwnfpcra0le9090uk5t5qw7armt is wrong for questioning.
Now if you ask whether they are "safe and effective", or either or, I struggle to see how most are either unsafe or ineffective.
Where's the risk of say, a tetanus shot?
As with everything injected or consumed, the risks depend on the risk profile of individual ingredients.
Formulations contain adjuvants, so from a risk perspective you can only increase it, because they are toxins.
Thetanus injection in DTaP can have Thiomersal which is mercury, or aluminum - depending on SKU. 
I understand. But it seems the primary argument boils down to whether the medical apparatus can be trusted for various datasets. For example, perhaps mercury is an adjuvant but wouldn't the medical community only use it if it's risk was so low.
