Has anyone actually had a live vaccine while on Humira?

Been on Humira for about 13 years now for Crohn’s. Recently had a baby in September and when I had my bloodwork done while I was pregnant I show no immunity to Rubella anymore so they suggested I get the MMR vaccine if I want until they realized I’m on Humira and said oh you can’t. I’m starting to freak out about these measles outbreaks although they were specific about rubella but still makes me nervous. But is it like 100% no you can’t have live vaccines while on this or have some people risked it? Obviously going to talk to my Gastro doctor about it but was curious is anyone has been in similar situations.
