From the Research
Adults aged 65 and older are generally eligible for the MMR vaccine if they lack evidence of immunity to measles, mumps, or rubella. The most recent and highest quality study on this topic is from 2023, which assessed the safety of the MMR vaccine in adolescents and adults 1. According to this study, the MMR vaccine is safe for use in adults, including those over 65 years old, with serious outcomes being rare and non-serious outcomes being mostly mild and self-limiting. The CDC recommends that adults born before 1957 are typically considered immune due to natural disease exposure, but those without documented immunity may need vaccination, especially before international travel or during outbreaks. For eligible seniors, the standard MMR vaccine dose is the same as for younger adults: a single 0.5 mL subcutaneous injection. Some key points to consider when determining eligibility for the MMR vaccine in adults over 65 years old include:
- Lack of evidence of immunity to measles, mumps, or rubella
- Born after 1957 or without documented immunity
- International travel or outbreak situations
- Healthcare workers or other high-risk groups
- Severely compromised immune system, pregnancy, or certain blood disorders It is essential for seniors to consult their healthcare provider before receiving the vaccine, particularly if they have any underlying health conditions or concerns. The vaccine works by introducing weakened forms of the viruses to stimulate immunity without causing disease, providing protection against these potentially serious infections that can have more severe complications in older adults. Overall, the MMR vaccine is a safe and effective way to protect against measles, mumps, and rubella, and adults over 65 years old who lack evidence of immunity should consider vaccination, especially in high-risk situations.
