Just thought I'd add some things I've noticed while playing the new and improved medical profession.
My sim is currently level 5 in the profession. At around level 3 I believe I was prompted to do a vaccination clinic. I hadn't read up on it and thought it was something I had to do AFTER work, but after the work day was over, I couldn't find the location to do it. So I don't know if you miss it during that work day you can't do it the next work day I guess.
The second prompt I got was to go to the Criminal Warehouse and do a lecture of some sort telling them about "their medical benefits" or something like that. I noticed that while I was doing the lecture my job performance bar was going down, but when I was done and went back to work, it went back up to where it was...and higher...before doing the lecture. I don't know if that was a glitch but I thought that was interesting.
Thirdly, as Pam mentioned, sometimes when your sim is out another sim will start "not feeling well" or something of that sort. When this happens, it will pop up with the other messages, for me some lady said "I'm starting to not feel so well, I wish there was a doctor around." Well, this happened right after she got out of work and I wasn't really paying attention, plus there were other messages saying the standard "your sim left work" and made such and such dollars, so you really have to be on the look out. Since I missed it, I then got a red pop up saying the medical community would not be pleased with me for not helping whatever-her-name was.
Just thought I'd add my experiences so far
I'll add more if I find anything else interesting hehe.
Happy Simming!
