I wonder how many minutes of that is actual talk about vaccines, their possible side effects, etc.
Coz i know a lot of people are told to consult their doctor regarding weight loss, when in reality they arent taught anything about how the body absorbs nutrients or the biology of specific food groups. (At least i heard a doctor say he (and every doctor he had asked) had more or less nothing on that subject, except a little summary of the official guidelines)
Anyways
Vaccines are great, but.. they arent actually made or approved by random clinical practitioners.. they are usually made by biologists. Which is a different education (of course with some cross over, obviously)
Why is who's making them important? A pediatrician is someone who's field is child medical care, including vaccines. I can guarantee she's pretty up to date in the literature surrounding vaccine efficacy and dangers to children. Part of being a doctor is learning to read studies and interpret them, and also keeping up to date with the literature, especially in your field.
For your example, your doctor might not know the answer to the exact question you ask, but they have training on how to get the answer that an average person doesn't. They should understand sigma levels of studies and what types of trials are better or worse for determining cause and effect. They (hopefully) won't just accept the first Google result that pops up. They also can recommend you to see a specialist if it's out of their domain.
Thanks for your bullshit anecdotes. Next time your house is on fire tell the firefighters you'll wait for the people that made or approved their fire hose.
