there  was  a crowdsourced vaccine,   
   that could be created regionally by  
    most   pharmaceutical  companies    
   without much effort,  and  it  was   
   estimated   that   it  had   saved   
       tens     of      millions.       
                                        
 but it  was not officially recognized by 
 the  world health  organization,  and as 
 such did not give  what  the  sanctioned 
 (and   unobtainable)   ones   did:   the 
 subskin chip that  would let  you  enter 
      (or      leave)      cities.      
                                        
  and that's why, eventually, we would  
   create  our own chips.  they  were   
  larger than the official ones, and a  
    little   unstable,   and   needed   
   maintenance.   but  they  worked!    
  or, they would work together with a   
  little something to make the  guard   
     look     the    other     way.     
                                      
                                      
                                          
   but the scanner showed green, so...
