Which individuals are recommended to receive both Hepatitis A and B vaccines?

The recommendation for individuals to receive both Hepatitis A and B vaccines is particularly emphasized for those at higher risk, including intravenous drug users and gay men. This is due to their increased likelihood of exposure to the viruses. Hepatitis A is primarily transmitted through the fecal-oral route, often through contaminated food or water, while Hepatitis B can be transmitted through direct contact with infectious body fluids.

IV drug users are at risk for Hepatitis B due to sharing needles, while gay men may have a higher incidence of Hepatitis A and B due to certain sexual practices. Public health guidelines often prioritize vaccination in these populations to reduce transmission and protect community health, making this the most fitting answer in the context of who should be recommended for these vaccines.

Other groups, though they may also benefit from vaccination, are not universally included in the high-priority recommendation. For instance, healthcare providers are recommended to receive vaccines due to their exposure risk, but the vaccines are not limited to them alone. The choice suggesting all adults lacks the specificity necessary for targeted vaccination strategies. Similarly, while travelers to endemic areas are advised to get vaccinated, this recommendation does not encompass everyone who may be at risk of exposure as identified in option B.
