  Probably not, theres been some needleless vaccines before that did ok. If anyone has done time in the military you’re probably familiar. Also any loss in efficacy could probably just be offset with higher concentrations

    First of all, thank you for taking the time help me understand. I didn’t know about past vaccines that used the system.

      The smallpox vaccine was put on a sugar lump that children then ate (It really was a different time) And even after going through the digestive tract it still worked.
