I also had no problem with getting mine - just had to book an appointment for it. Like some others, had a sore arm for a few days!
I am not always a big fan of conventional medicine, however, as someone else mentioned, I wonder whether I would have been quite ill without it. A little while back my partner came down with a dreadful cold which lasted ages - and I only had some symptoms for a couple of days. Similarly, I have had a cold since Thursday, but it was only bad for one day and I have had no change whatsoever in my BS. Also, I work in schools so bugs are everywhere, but I seem to have been less ill than a lot of my colleagues.
So at the moment, I am a fan of the flu jab!
