dendridic vaccine plus virus

Dear all,
we are planning on getting the vaccine with Van Gool for my 17-year old pretty soon. I know he is using  Newcastle virus with it, but I wonder if this would be the most effective/aggressive option. I have seen mixed reports on its efficacy, so I wonder if tetanus shot or Hilton would be a better option to add to the vaccine. From what I read, tetanus seems a lot more effective. As much as I trust Van Gool's expertise, I still can't fully put my faith into any one treatment if there is a possibility of something working better. I am sure Van Gool would insist on his approach, but I wonder if this is because he truly believes it is better tan others ( such as tetanus) or because this is the only protocol they use at the moment. Would anyone have an opinion on that? Thanks!
