Hepatitis B vaccination is typically offered for which group of individuals?

Hepatitis B vaccination is primarily intended for at-risk workers, such as healthcare personnel and others who may be exposed to blood or bodily fluids in their line of work. The vaccine is highly effective and reduces the risk of acquiring the infection significantly, making it essential for those in high-risk groups.

Employers often provide this vaccination free of charge to ensure that their employees are protected against the virus, which can lead to severe liver disease. By immunizing at-risk individuals, organizations can help prevent outbreaks and minimize health risks associated with hepatitis B exposure.

The other options do not accurately reflect the guidelines for vaccination. While it's beneficial for many to be vaccinated, not all employees need the vaccine, particularly if their job does not involve exposure to blood or bodily fluids. Additionally, providing the vaccine solely to those with prior infections is not effective, as unvaccinated individuals who have not been previously infected also need protection. Older individuals may have different vaccination recommendations based on their health status, but age alone does not determine the necessity for vaccination.
