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...
