Most people who vaccinate will tell you that the vaccine isn't 100%.
Even the manufacturers write this. Here's a quote from data sheets for a
marek's vaccine:
"Under certain conditions, for example extreme disease pressure &
variant challenge, fully immune birds may succumb to the disease.
Therefore successfully vaccination may not be synonymous with full
protection in the face of a disease challenge."
Vaccinated birds can carry the field virus if they've come into contact
with it & be infectious to non vaccinated stock. Most Marek's vaccines
seem to be made from the turkey herpes virus, either live or attenuated,
raising with turkey poults to gain immunity could be another option?
