How many doses of M-M-R II (Measles, Mumps, and Rubella vaccine) should a 77-year-old female receive if she got one dose in 2015?

From the Guidelines

The 77-year-old female who received one dose of M-M-R II vaccine in 2015 does not need any additional doses. For adults born before 1957, including this patient, routine MMR vaccination is not recommended because they are generally considered immune to measles, mumps, and rubella through natural disease exposure that occurred before vaccines were widely available 1. The single dose she received in 2015 was actually more than what is typically recommended for her age group. This dose likely provides adequate protection if she was somehow not naturally immune. The Advisory Committee on Immunization Practices considers adults born before 1957 to have presumptive immunity to these diseases, so no further vaccination is necessary 1. However, if this patient is in a high-risk setting during an outbreak or has other specific medical conditions that compromise immunity, different recommendations might apply, and she should consult with her healthcare provider about her individual circumstances. Some key points to consider include:

• Adults born before 1957 are generally considered immune to measles and mumps 1
• A second dose of MMR is recommended for certain groups, such as students in postsecondary educational institutions, healthcare workers, or those planning to travel internationally 1
• The patient's single dose of M-M-R II in 2015 is sufficient for her age group, and no additional doses are needed unless specific risk factors are present 1

From the Research

M-M-R II Vaccine Doses for a 77-Year-Old Female

• The user is asking about the number of doses of M-M-R II (Measles, Mumps, and Rubella vaccine) a 77-year-old female should receive if she got one dose in 2015.
• According to the provided studies, there is no specific information about the recommended number of doses for a 77-year-old female who has already received one dose of M-M-R II in 2015 2, 3, 4, 5, 6.
• However, study 6 discusses the administration of a third dose of MMR vaccine in certain situations, such as identified seronegativity and during outbreaks, but it does not provide information about the recommended number of doses for individuals over 65 years old.
• Study 5 provides updated recommendations for mumps vaccination, but it does not address the specific question of the number of doses for a 77-year-old female who has already received one dose.
• Study 4 assesses the effectiveness and safety of MMR vaccines, but it does not provide information about the recommended number of doses for individuals over 65 years old.
• Study 3 evaluates the immunogenicity and safety of a second dose of MMR vaccine in individuals 7 years of age or older, but it does not address the specific question of the number of doses for a 77-year-old female who has already received one dose.
• Study 2 discusses the persistence of antibody to measles, mumps, and rubella vaccination, but it does not provide information about the recommended number of doses for individuals over 65 years old.

Summary of Findings

• There is no specific information about the recommended number of doses of M-M-R II for a 77-year-old female who has already received one dose in 2015.
• The provided studies do not address the specific question of the number of doses for individuals over 65 years old.
• Further research or consultation with a healthcare professional may be necessary to determine the recommended number of doses for this individual 2, 3, 4, 5, 6.
