<p>S2 had it at 18. It was required by his college. No ill effects, except a little soreness in his arm, but not as bad as a flu shot. Wasn’t required or promoted as much for older S.</p>
<p>My insurance paid for vacinations until age 18. My son got his a week before he turned 18.</p>
<p>All three kids had it, no side effects. This is a no-brainer (although I do understand your hesitance).</p>
<p>Git 'er done.</p>
<p>^^^^Ha ha, I love Larry the Cable Guy.</p>
