Hepatitis B is a highly infectious disease. It is often fatal, and, when it isn't, it requires a lengthy recovery. Lifeguards are at risk of contracting hepatitis B because they can come into contact with the body fluids of strangers.

The hepatitis B vaccine consists of an initial injection, a booster shot one month later, and a second booster shot roughly 11 months after the second shot. You must get all three shots to have the best chance of becoming immune to hepatitis B.

The Occupational Safety and Health Administration (OSHA) requires that each lifeguard either receive the vaccinations for free through the beach patrol, provide proof that he or she is on schedule to complete the series of injections at his or her own cost, or sign a form declining the right to receive the vaccinations. Minors must have the signature of a parent or guardian to receive or to decline the vaccinations.

LBTBP makes the vaccinations available on two evenings in July and two evenings in August. In July, new guards receive their first injection and returning guards receive their third. In August, new guards receive their second injection. If you miss your scheduled injection, the only way you will be able to keep your job is to either sign a declination form or to pay to receive the injections on your own (which costs roughly $120).
