Sorry probably already been discussed but I have just received a letter inviting me to take the swine flu vaccine on the 22nd. I really don't know what to do for the best! I've read that you feel really ill after and can suffer with a really painful arm.. But things I've heard in the news etc have left me feeling 'scared' about having it.. Just wanted to hear from people who are in the same situation as me, what did you do? How did you feel after if you had it?
