The effects of alternative vaccine compositions on the outcomes of the cost-benefit analysis were assessed. Five modifications for PCV10 and one for PCV13 were considered

Conclusion: The assumption about serotype 3 in PCV13 is crucial. In addition, assumptions about the role of 6A in PCV10 is important.


 PCV13adv.inIPD 
   = (IPD under PCv10) - (IPD under PCV13)
   if positive, PCV13 saves IPD compared to PCV10
 price of PCV13 
   =  if PCV10 price set at 20e, what is the matching price for PCV13?
 ICER 
   = incremental cost-effectiveness ratio for PCV10 at price 20e
    (in this table, this value is also average cost per QALY)
