Emily got hers the end of August. They were not routinely giving them that early (due to not yet having a large supply) but she was in for her yearly checkup and given her risk factors they felt it made sense to do it then. My other kids are going in next week for theirs; my dh and I are going next month (the soonest our pcp is offering them.)
As posted above, immunity lasts for the whole year, we were told by the ped last year- NOT the much shorter time frame many believe. Here is an excerpt from an article I found...
<a target=_blank class=ftalternatingbarlinklarge href="http://abcnews.go.com/Health/ColdandFluQuestions/story?id=5677892">When Should You Get A Flu Vaccine, And How Long Does It Last?</a>
<div class="FTQUOTE"><begin quote>The immunity from the vaccine actually lasts for a substantial period of time. In past years people used to be concerned that the immunity would fade but we have much better data now that supports that immunity actually can extend throughout the influenza season into the spring, and in many cases actually into the following year. Still, we want everybody to get influenza vaccine each and every year since the vaccine is slightly different from year to year and you want maximal protection for that upcoming flu season as quickly as possible and as early as possible.</end quote></div>
