Vaccination and Public Health
There have been a lot of debates about vaccination. There is a doctor in the USA who runs a blog (see link) that posts about vaccination.
I am generally a supporter of the principles of vaccination. In a sense the debate about MMR shows how things can get a little flakey argument wise. There are adverse reactions to vaccinations, but they are almost invariably a lower risk than the adverse reaction to the underlying disease.
I am uncomfortable with having a legal requirement for vaccination, but I do generally encourage people to have vaccination. The debate about TB vaccination is an interesting one. I have been arguing that it should be made more widely available to those people who request it.
Dr Flea's arguments, however, are worth reading (see link).
