Most doctors don't really understand scientific reasoning and the practice of science. They may be very good at what they do in some strictly bounded domains, being able to accurately diagnose most common diseases in their specialties and correctly indicate the most commonly useful treatments, but when faced with something new or unusual they usually need to have some external help as they are not intellectually prepared to move away from some very well defined protocols. And this is mostly ok. Most disease in human beings is common and straightforward to treat, and when it is not, we don't expect primary care doctors to be able to treat them or to have a definite opinion on that. The more complex and severe the disease, we can still have protocols, but they are less definite, more varied, and require far more expert criteria to be adapted for a given patient and his clinical situation. Concerning vaccinations, most doctors don't really understand the more intricate aspects of immunology or virology, but as most vaccines are indeed very safe after as much as ten years of testing, they could recommend them as safe and effective while knowing the contra-indications because the system had correctly worked and they were given good information by the authorities. Enter the under-tested gene therapies called COVID vaccines, they are sold the same discourse by the authorities, but now this discourse is not truthful, we don't actually know the real risks, and people were subjects in a experiment which is still, and which will still be ongoing for a few years. But, most of those doctors are afraid to say they really don't understand this. They're afraid of going against the authorities, and when you challenge their beliefs they get outraged, because they are acutely aware they really have no fucking idea what they are talking about, they don't have the required curiosity to try to understand it and probably you, the patient, seems to have more information that what they do.
