You don't need their blood or body fluids, just a little of their virus but I'd probably select people who could be blood donors for that reason. Even when the government gives the vaccine, the virus often spreads to others without them trying. That's the good thing about this vaccine, it's just a live unattenuated virus and doesn't really require the government to spread it.

That is one reason why it is better to have children vaccinated first. They are much less likely to have nasty "social diseases" than adults. Transferring the vaccine from child to adult should be much safer than adult to child or adult to adult.
