I have spoken to local law enforcement and if you don't want the Federal government on your property asking about vaccines, they advise you to post a no trespassing sign in a visible location. This is a prerequisite to be able to charge someone for being there against your will.
Door-to-door inquiry about vaccine status is not an enumerated power under Article 1, Section 8. Health is a power delegated to the States and you are under zero obligation to open the door.
