During a public health declared mumps outbreak, a 21-year-old college student with a history of 2 MMR vaccine doses as a child wants to know if she needs a dose of MMR now. Which of the following is the best response?

The best response in this scenario is to affirm that the 21-year-old college student should receive a dose of MMR since there is a declared mumps outbreak. Current recommendations from health authorities, such as the CDC, indicate that during an outbreak of mumps, individuals who are at increased risk and have previously received two doses of the MMR vaccine may benefit from an additional third dose. This is particularly relevant for young adults in close living situations, such as college dormitories, where the risk of transmission is heightened.

Receiving an additional dose can help to enhance immunity in populations already vaccinated and reduce the spread of the virus during an outbreak. This approach is intended to improve community protection and control the outbreak effectively. The history of two doses alone may not provide sufficient immunity in certain situations, thereby justifying the need for a booster during public health emergencies related to mumps.

The rationale behind the other choices stems from specific considerations regarding outbreaks. Suggesting that a third dose is only necessary for rubella or measles outbreaks misrepresents current public health guidelines. Additionally, stating that all college students should have three doses of MMR is misleading, as not all individuals require additional doses outside of outbreak scenarios. This underlines the importance of tailored vaccination strategies
