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...
