Which of the following is true of hepatitis B (HBV)?

Hepatitis B virus (HBV) is a significant public health concern, particularly in healthcare settings. The statement regarding the vaccine for HBV is accurate because there is a highly effective vaccine available that significantly reduces the risk of contracting the virus. Vaccination is especially important for healthcare workers who may be exposed to blood-borne pathogens, as it helps prevent potential transmission of the virus during exposure incidents, such as needlestick injuries.

The vaccine works by stimulating the immune system to produce antibodies against the virus, which protects individuals from becoming infected. This preventative measure has been instrumental in reducing the incidence of hepatitis B infections in both healthcare personnel and the general population.

In contrast, other statements suggest a misunderstanding of the severity of HBV. While some may perceive HBV as a minor disease, it can lead to serious health issues, including chronic liver disease, cirrhosis, and liver cancer. This underscores the importance of vaccination and awareness regarding the potential consequences of HBV infections.
