Ultrasound can push vaccines into the body without needles (www.newscientist.com)

Vaccines can be delivered through the skin using ultrasound. This method doesn’t damage the skin and eliminates the need for painful needles. To create a needle-free vaccine, Darcy Dunn-Lawless at the University of Oxford and his colleagues mixed vaccine molecules with tiny, cup-shaped proteins. They then applied liquid mixture to the skin of mice and exposed it to ultrasound – like that used for sonograms – for about a minute and a half.

Yeah, exactly. And I agree that there's separate categories for skill, dedication, and niceness. Some folks are damn good but lazy and don't care, others make up for being "only ok" by trying really hard and caring a lot, and some are just friendly when they screw up. It's nice to have more than 1 of those 3 at a time. Someone in my family went to a weight loss doctor and asked me to come along. She was the friendliest doctor I'd ever seen... and the appointment finished with "I'm really lost. I don't think there's anything else we can try right now. You're doing everything right". Don't know WHAT that was in the spectrum of skill and dedication. Maybe it's true, maybe she was just giving up. But from what I've seen/heard, it's definitely better than "well try harder, eat less, and workout more" that heavier patients hear from doctors who don't even ask what they're eating or what their workout regimen looks like.

I don't have to deal with a lot of that stuff you do, but I can imagine it since what little I deal with has shown me multiple sides of people (doctors too, I suppose).

My worst was my GP/PCP saying all men are a little ADHD. I got an official diagnosis with ease. Now I use a doctor recommended by a friend and she's fantastic. All my docs are women now, and I only use men for mental health stuff. It's worth it hunting down the right people if you can. I'm kinda lucky with my insurance. I use a badass local pharmacy, too, and their competence is mind blowing compared to big corporate pharmacies.

What fucked me up with the nurse was that the first time I met him he just finished the infusion. Took the tape off and pretty much dropped the IV rig. It just bruised a bit, but was distressing to watch. The second time I saw him I was like "oh fuck oh shit" but he had no problems. Got it on the first attempt. Painless. He's just way too chill on the back end.
