Nice idea, but there's no way something like this would pass FDA. Even for the live VSV Ebola vaccine that contains no Ebola at all in it, except for the encoded spike, it's recommended for a doctor to do administration, and it's not commercially available, so you have to justify your need for it to the federal government. You are also supposed to avoid close contact with anyone else for quite a while after, to prevent transmission of the vaccine virus.
