OF course not. He was in prison in North Vietnam, not in the south. No VC around there, just NVA (North Vietamese Army). McCain was shot down in late October of '67. Within six months, after Tet of '68, there weren't all that many VC anywhere. Except the "pet" VC that NV pretended were an independent political "Front", like Madamn Binh who Kerry met with.
OK, but I still dont see how one can equate McCains service with Kerrys conduct after the war.
