The current vaccines for COVID are actually more effective than well established vaccines like the flu shot, shingles shot, etc. Those shots are in the 50-60% efficacy range. Even shots for things like HepA and B only have uptakes in the 80% range after the full course.
The idea that the COVID vaccine is somehow a failure is asinine. Right now in my state, the ratio of vaccinated to unvaccinated patients hospitalized with COVID is >9:1. That's pretty darn good. To put it simply, the only reason we're still in this mess is stupid people ruining life for the rest of us.
This is the dumbest thing I've ever heard. All doctors generally practice using the best available research. However, its unlikely a specific doctor is studying your specific disease and so its stupid to expect all doctors to be able to pull up their personal papers on your personal disease. All doctors should be practicing using the best available research and data. Its almost by force actually because insurance companies do monitor requests for testing and medications and won't pay for things in general that don't have evidence behind it. Basically if a doctor is out there doing stuff not supported by the research and something bad happens leading to a lawsuit, he has zero defense and will lose the case hard. In malpractice suits, its doctors testifying against other doctors in a nutshell and the only thing to really talk about is what the evidence shows and the person involved either didn't follow it or did. You can at any time ask a doctor to show you the data behind a recommendation and they should be able to show you an article or guideline statement supporting his recommendation. However expecting your doctor to personally be researching your disease is the stupidest thing I've ever heard.
As for the percentage of docs doing active research or not, that has to do with the distribution of academic physicians vs private practice physicians. Some docs go into academics. They do it because it's slower paced, they don't have to see as many patients and they have freedom to study things they think are interesting. However it pays less, there's pressure to compete and apply for grants, and there's a lot of uncompensated work you have to do like give talks, lectures, QI work for your organization, national committee work, etc etc. I think the pressure to apply for grants is probably the major detractor academic medicine and so many people go into private practice which is a different lifestyle: you see patients pretty much exclusively but your get paid nicely and don't have any uncompensated side work to deal with. There's also the fact that training programs are increasingly slanted towards private practice careers because of doctor shortages nationwide.
