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...
