how long can hepatitis b live outside the body
The hepatitis B virus can survive outside the body for at least 7 days. During this time, the virus can still cause infection if it enters the body of a person who is not protected by the vaccine. The incubation period of the hepatitis B virus is 75 days on average, but can vary from 30 to 180 days.
1 Understand that hepatitis B vaccination-induced protective antibodies can last for up to 15 years, but appear to fall off over time.nti-HBs levels decreased in the study population from a mean concentration of 822 mIU/mL after vaccination to 27 mIU/mL at 15 years. Higher levels of anti-HBs were noted in males, individuals with higher initial anti-HB levels, and those who were older at the time of vaccination.
