Hepatitis B vaccine is a vaccine that prevents hepatitis B.[13] The first dose is recommended within 24 hours of birth with either two or three more doses given after that.[13] This includes those with poor immune function such as from HIV/AIDS and those born premature.[13] It is also recommended that health-care workers be vaccinated.[14] In healthy people, routine immunization results in more than 95% of people being protected.[13]
