Question about Hepatitis B form

<p>So I was gonna submit the Hepatitis B form today since it said that the 15th would be the deadline but then i saw this message </p>

<p>"Your Hepatitis B immunization certification has either been submitted or you have met the age requirement. "</p>

<p>I thought that everyone had to get the injection no matter what age? What was the age requirement?</p>

<p>Student health services says this “Effective January 1, 2000, the California State Legislature mandated first-time enrollees at the University of California, who are eighteen years of age or younger, provide proof of immunization against Hepatitis B prior to their enrollment.” on their website. Perhaps if you are 18 years or older, you do not need to provide proof of immunization?</p>
