Management of Non-Immune MMR Components and Hepatitis B

MMR Vaccination Strategy

The American College of Physicians recommends that healthcare workers born after 1957, like this 55-year-old female, receive one dose of MMR vaccine immediately to address lack of mumps and rubella immunity, regardless of measles immunity status 1, 2, 3, 4
For healthcare workers, a second dose of MMR is recommended, administered at least 28 days after the first dose, to ensure adequate mumps protection 1, 5
Women of childbearing age who lack laboratory evidence of immunity should receive MMR vaccine, with particular emphasis on counseling regarding congenital rubella syndrome 2, 3, 4

The Centers for Disease Control and Prevention recommends that individuals with a "non-reactive" hepatitis B result, indicating no immunity, initiate the complete 3-dose hepatitis B vaccine series 9
The hepatitis B vaccine series should be administered as follows: Dose 1 immediately, Dose 2 at least 4 weeks after the first dose, and Dose 3 six months after the first dose 9
Post-vaccination testing, including hepatitis B surface antibody (anti-HBs) titers, should be performed 1-2 months after completing the series to confirm adequate immune response 4, 9

The American College of Physicians advises against assuming birth before 1957 confers immunity for healthcare workers, as documented immunity or vaccination is required 1, 5, 10
The Centers for Disease Control and Prevention recommends against delaying MMR vaccination or attempting to give separate mumps or rubella vaccines, as MMR is the vaccine of choice when recipients may be susceptible to more than one component 1, 8
