Why does CDC recommend HepB vaccination of adults in settings (such as most pharmacies) where triple panel hepatitis B screening is not available?

Because HepB vaccination is a series of 2 or 3 doses of vaccine, and because most older adults need vaccination, we recommend initiating the series whenever and in whatever setting the opportunity arises. There’s no downside to vaccinating, but delaying vaccination could leave someone vulnerable to infection. Patients who are vaccinated should be informed of the recommendation for a one-time triple panel screening test in the future.
