I believe that IPV vaccine is avaliable with VVM 14 and 30. VVM 14 color changes faster, can we use IPV with VVM 30 for immunization program? Any price difference between VVM 14 and 30?
Can someone help to respond?...

I believed even countries maintaining high routine immunization coverage for OPV and IPV also detected cVDPV 3 or Type I poliovirus in enviromental sample, so whether cVDPV or type 1 polio virus is imported or mutated originated strain within the country.
