I feel like you should be warned that the way your pediatricians are most likely to keep themselves out of that legal battle is by telling you that you have to find a new pediatrician. (Also, what is notarizing this document supposed to do? I was a notary for a long time, and if you brought me this to notarize, I would collect your fee and stamp your letter, but I would also have to advise you that all I was doing was saying that you proved your identity to me and signed this of your own free will. That doesn't make your document legally enforceable. It just puts a pretty stamp on it.)
Family courts generally want both parents to have a say in medical decisions, and they'll encourage parents to come to mutual decisions. If that appears to be impossible, they may give medical custody to one parent or another, and make that parent the only one who can consent to medical treatment. That would make it possible for you to make sure your kids don't get vaccinated (if a judge awarded you sole medical custody, and not your husband), but it means that if your child was ill or injured while in your husband's care, he couldn't take them to the doctor on his own, and the ER could only treat your children if their conditions were immediately life-threatening, if you weren't there. Courts are generally very reluctant to give parents sole medical custody for this reason.
If your husband has changed his mind on vaccines, I'm of the opinion that the power play here is him talking about it. If he's that set on it, he could call up the pediatrician, and bring the kids in. Instead, he's arguing with you. I think the point of the discussion for him is not the vaccines, but the argument. If you call his bluff on that, he's a little more likely to stop bluffing, so I wouldn't necessarily call his bluff... but I'd look at how the argument usually goes, and see if there's a way to cut him off from whatever he's getting out of it.
Edited to add: He's waiting until August to divorce you so that YOU can afford to move out? Talk to a lawyer now, and discuss whether it makes more sense for him to leave the family home. This does reinforce my power play theory.
