There is a way around this from what I understand.
A religious exemption is based on religious beliefs you testify too having at the MOMENT YOU SIGN THE WAIVER. So if in the past you partially vax'd a child, and then changed your mind about vax's, and went to go get a religous waiver, that is NOT A CONTRADICTION. It is unimportant how long you had your faith, 2 seconds or 2 days before signing the waiver. The waiver is a testament to the *future* vaxing of your child...not the *past*.
What is *NOT* accepted usually is a "partial vax" faith. Legally, you either believe in them or not. So, get all the vax you want for your child BEFORE signing the waiver. That is what I have been told.
Hope this helps,
