as for the other guy,
I see your point, you want to access to the best health care possible. I'm sorry if I came down too hard on you with my views, maybe I should tone it down a little (just trying to make these threads more interesting).
However, I still think your mindset is fundamentally rooted with elitist views. You stated that you wouldn't even go to a practice that employed NPs/PAs, for fear of having to see the one of them I presume. You're writing off the entire practice for this reason? You can still see the doctors working there, you know. Keep in mind, the context of this thread - physicals and vaccinations. NPs and PAs have essentially the same training for H&Ps and vaccinations as doctors. They can handle it.
If you were in your mid twenties and healthy, it's not efficient or considerate. It doesn't make sense to necessitate 7 years of medical training for a physical and vaccinations. Clear and simple. But you got me, my guess was wrong, and you're older.
As for the shortage of physicians, obviously this depends on where you live. but yes, there is a shortage.
Yes, credentials are important to beauracracies. Experience is important in real life. I won't patronize you, as you're old enough to know this by now. But it's important to remember.
