       | Very cool, but what would happen if that molecule was small pox?

           | Turns out smallpox vaccines are a lot older than I thought.
           | They might have not looked exactly like that in Victorian
           | England, but an iteration of it did already exist. Guess
           | that's why they cover up tattoos but not smallpox scars.

       | 
       | Super exciting work nonetheless.

         | But really what they found here should maybe be called an

         | and a protective response should be mounted to it)
