Which is true about the Hepatitis B vaccine?

The Hepatitis B vaccine is key in preventing Hepatitis B virus (HBV) infection, particularly among healthcare workers who may be at higher risk of exposure due to their profession. The correct answer reflects the fact that it is mandated for all healthcare employees who have exposure risks, in alignment with guidelines from the Occupational Safety and Health Administration (OSHA) and the Centers for Disease Control and Prevention (CDC). These regulations are put in place to protect both healthcare workers and their patients from potential transmission of the virus.

Being vaccinated is important because Hepatitis B can lead to serious liver disease, and vaccination significantly reduces the risk of contracting the virus if workers are exposed to blood or other potentially infectious materials. Therefore, it’s not just a recommendation but a requirement in many healthcare settings, ensuring a standard level of safety.

In this context, the other choices do not correctly reflect the policies surrounding the vaccine. It is not merely voluntary for healthcare workers since guidelines emphasize the need for vaccination in this group. Additionally, while post-exposure prophylaxis is important after a needlestick injury, the vaccine should be administered prior, as a preventive measure rather than as a reaction to an exposure. Lastly, there is no age restriction like being only required for those over 40
