This is just asking for home invasions via enterprising hoodlums masquerading as Biden Vax personnel. IMO, the best thing to do is to deny any entry. If "legit" vax personnel gain entrance to your front steps, don't let them in and query them on who they are, where their authority comes from and what info they already have about you. This way you will be ready to sue the government for HIPPA and human rights violations. Do not give out any info including your own vax status.
