Additional Information: GSK Receipt Date: 07-FEB-2025 The patient had a negative titer test, so the physician asked us what was the appropriate booster volume dose for Engerix-B. During the call the health care professional informed that the patient complete their Engerix-B vaccine scheme as a child, but due to the titer negative test, they were looking for the appropriate Engerix-B booster volume dose. Health care professional mentioned that the patient had the titer test in 02-Oct-2024.
