Backstory: This spring I had to go to court to prevent my two DDs from being inoculated with TDaP when my ex-husband tried to force the issue when his new spouse was expecting a baby, and he suddenly became fearful of Pertussis (full disclosure: there was a pertussis "outbreak" in our area, consisting of 2 children in a neighboring school district that were diagnosed with pertussis, but it was on the news as an "outbreak."). We share custody 50/50 and he has always been involved in medical and school decision; we were, in general, on very amicable terms, and before this court case, we had NEVER seen the inside of a courtroom for any issues with child support, custody or anything. Prior to last spring he had signed off on school exemption forms and our 9 year old has never had any shots in her life, which he had always gone along with. Our 11 year old had the first few rounds of shots long ago as a baby before we made the decision (together at the time) to forego future shots. So they'd been vax-free for like 10 years when he suddenly took me to court over it. Being low-income it was a huge hardship to hire a lawyer and defend myself, but it paid off and we won the case. However, I no longer trust him on the issue of vaccines, because of this experience, especially because he hinted that TDaP was not the only thing he wanted them vaxed for, and he mentioned that some day they might travel to France and since there had been measles outbreaks there, he'd want them vaxed for that and preferably caught up on all their shots. But after the court case, he stopped talking about vaccines; there baby is healthy and breastfed and all seems (relatively) back to normal amicable relations.
Fastforward to this morning: I get a call saying that his wife was just invited to Paris for a work-related trip and they want to take all the kids and make it a family trip. They don't have much time to work with, because the event is in early December, so it's about 6 weeks til they'd have to depart. Thus he said he wants me to meet him at the post office today to sign for the DDs' passports. I did some research revealing that "required" vaccines for travel to Europe are not actually required. However, I am concerned about how to ensure that our unvaxed status is respected. Is there some waiver or something I need to fill out at the time of passport issuance? If I give my permission for the passport, I'm not tacitly agreeing to shots am I? Any advice on how to be sure vaccines aren't foisted on DDs in this situation would be appreciated! TIA!
