9/12    Some vaccine requires 2 shots, 6-1 year apart. When will someone
        develop protection? A few weeks/months after the 1st shot? Or
        only after the 2nd shot?
        \- are you talking about say Hep A? some shots are configured
           to require boosters for longer term protection. so you will be
           protected for a while after the first shoot but if you get both
          you may be protected for 10-20 yrs.
           you may be protected for 10-20 yrs. the exact schedule recommended
           depends on the disease and the vacc type.
           \_ What about b that requires 3 shots? Are you protected after the
              first shot?
              \_ Each time your body reacts to an antigen, some B cells
                 targetting that antigen go into an inactive state with high
                 longevity.  By reactivating them with boosters after the
                 initial exposure reaction is over, more storage cells are
                 created, often with different ways of targetting the same
                 antigen.  So when you're infected by an active virus, your
                 body has a head start in dealing with it.  The boosters
                 give you even more of a head start, so that possibly your
                 body can fight off a virus before there are any symptoms.
                 \- You should go ask an immunology professor about this.
                    Or maybe Peter Deusberg. But stand with your back to
                    the wall.
                    \_ Or wear a chestity belt backward.

3/21    what are these virus phages? Can they be repurposed?
        \_ are you <b>insane?</b> you really want to start messing with
           recombinant <ul>rna</ul> crap when we don't even understand
           the normal virus lifecycle?
