<p>Goalie,
The “regular” flu shot is about 85% +/- effective as it does not hit all strains. Just the ones they felt most likely last year to hit now. Thus, every year people who get the shot, get the flu. However, odds are that she does have h1s1. </p>
<p>But, if her school has a large number of kids who are out sick, it might not be a bad idea to continue usage. $30 for most insurance plans and minimal side effects vs getting sick again.</p>
