God I hope those dentist lost their medical license forever. I am very untrusting of dentist in general due to issues like this. I remember my brother as a preteen had 6 teeth removed and my mom said she didn't think he needed it but she was trust the doctor always type. Later the doctor was found to be pulling teeth of kids on state insurance that didn't even have cavities.
Maybe the news and media need to get involved here. If they don't face any repercussions then I'll remember to cite that as to why people could be distrustful of doctors when it comes to vaccines and other things.
Every industry has cowboys. This study should just reinforce the notion that we should get a second opinion (or third, if the first two differ) on ANY major work being carried out by ANY profession.
To extend that line of thought, and steer it towards the second half of your comment: if you visit two (or three) doctors to seek advice about getting vaccinated, I think we can be sure what the consensus would be.
I didn't say that people shouldn't get vaccinated, just that it is understandable why people would have a general distrust towards doctors because of things like this. Maybe we should try not to ostracize people for having legitimate distrust.
