Husband and I don’t agree on kissing exposure

I have a medical background and am in school to further my education in medicine. I want to also add that I am a first time mom who worries about every little thing, so I do tend to be more cautious but also do believe in natural immunity and that exposure=growth.

I made a post a couple of days ago about not wanting anyone except my husband and I to kiss baby on the face for the first 6 months. Babies have maternal antibodies in months 1-3, and are most susceptible to illness in months 3-6 as they lose mom’s antibodies and build their own immunity. I THOUGHT my husband would be on board with the no kissing for the first 6 months or at least respect my opinion on the matter due to my background. Especially with the fact that my due date is in September during peak RSV and flu season. Nope, he thinks I’m being ridiculous and that the baby will be fine. He thinks I’m overreacting and that family (even extended) should be able to kiss the baby, and that I am being a “helicopter mom.”

My hormones are raging and I could scream. Bc all I hear is that he isn’t protecting the baby.

Has anyone experienced a difference in opinion on this? I know generally speaking, most people would agree with me on the matter. But I’m trying to look past this.
