I just had this answered the other day.

Kaeden had his first flu shot when he was about 18 months old.  For some reason the A.F. Base where he had it done ( I did also)  only gave him one shot when it was his first time receiving it. It was also my first time so I didnt know about the "two shot rule" when you get the seasonal flu vaccine for the first time.

Since then Kaeden was dx with Leukemia and EVERY year I tell the clinic that he never had that "two shot" series.  They said not to worry about it each year.  UNTIL this last week.  I once again reminded them that he only had one shot the first time.  His former nurse this time had a answer for me.  She said the CDC has come out with a new rule (or however you want to put it) that if you NEVER had the two shot series that you will have to at some point.

So since Kaeden had his first H1N1 and his second H1N1 isnt due till the end of November~ He will have to wait till the middle of December to get his first Seasonal flu shot and his second at the end of December.  I am not worried right now about the seasonal flu because it isnt really going around at the moment. So waiting till December isnt really a problem for me.

I just printed out an article from a canadian news site that there may be a good chance that the kids will only need the one dose of the H1N1 vaccine.  Apparently, they are finding that this one single half dose that they get is providing strong immunity and that they may not require that second half dose in three weeks.  As of yet, our hospital doesn't have directions in that regard, but the article did say in the coming days they will come out with the decision.

As for the seasonal booster, I'm not sure - where we live, they are doing the H1N1 first dose, then a week or so later the seasonal vaccine and then a week or so later the H1N1 booster.  I do know that every province in Canada has different recommendations so its up to where you live on how they decide to do things I guess.

The doctor says they don't think the booster is needed, as the immune response in kids has been strong.

I asked about the young cancer patients, and she said they haven't seen serious complications so far, and the tamilflu seems to be helpful.

They gave my son the seasonal flu shot during his visit. She said they do it then for convenience, and they are not too concerned about the prednisone.

My son will be getting two of both. He is 15 months...and while in his treatment, he didn't have any vaccinations because basically all the chemo was going void it anyhow. So, it may be because it's he first time, as he is also on the catch up schedule for shots, too. Anyhow, he's been off treatment for almost nine months - but is basically considered under the age of one because of treatment. Don't know if this helps. I do think next year will be different.
