Parents should agree, otherwise maybe it may be a case for family court? A TRO is not how these disputed are handled b/c a parent can’t get a TRO against another parent ostensibly to protect a child.
TRO wouldn’t target the wife, it would target the school/county health department/death shot provider. Only way to target the wife would be to file a petition for divorce with an emergency petition for temporary sole custody. Very poor chance of success most places on the facts given. Uphill battle even if he could find an anti-vax judge.
