See below: The majority of people who receive the Hepatitis B Vaccine (65%) do not experience any reactions to it. About 3% of those immunized will develop pain and tenderness where the shot was given; low-grade fever occurs in about 1% to 6% of vaccine recipients.

VIS Statement. There is a vaccine information statement put out by the cdc that lists it's indications. As a pediatrician, I think everyone should get the vaccine. It is universally recommended for everyone under age 19 and for many categories of others including those with more than one sex partner, household contacts of people with hepatitis b, people with chronic renal or liver disease and other categories.
Get a booster. If you have concerns about waning immunity, you can receive a booster dose. If you had the primary series or part of it, this will help.
Six months. Children can receive hep b vaccine starting at the age of 6 months.
Anytime. The original research on newborn hep b administration was done years ago in hawaii & it was one of the first states to see a decline in hep b disease across the population. It is commonly given now at birth, 1-2 m & 6m during infancy but can be given to older kids at any age. Those who missed the vaccine in childhood should look into it.
