I can't really even understand what this comment is trying to say. Vaccines aren't harmful. But doctors don't make vaccines, pharma companies do. And pharma companies would gladly hurt you. Conclusion: ???.
Interested does not always have to be financial. It is hard for a community to go back on its beliefs. So in all probability, it is possible that a doctor can ignore the negative effects of a vaccine they are seeing due to this and huge perceived peer pressure in talking against the current medical consensus (Which is, as stupid as it sounds, All vaccines are completely safe)
