Hi Shazza, I'm not sure about the pneumonia vaccine but we received the appointment card through for the seasonal flu and swine flu vaccine, the impression I have from the note is that the two are separate injections. They also mentioned that a booster would be needed for the swine flu vaccine 3-5 weeks later.
btw, we've decided that Jess won't be having the vaccine (swine flu or seasonal). It was a tough decision and not taken lightly but there were other issues apart from her diabetes that we gave consideration to when we made the decision.
