The following information is from ProMed.  You may wish to consider a third dose of MMR for high risk people.  Mumps exposure can be a risk when people travel internationally to some destinations.

CBS News reports on a resurgence in mumps infections throughout the
United States, with more than 2800 cases reported this year [2016],
nearly double the number of confirmed illnesses in 2015.

The University of Missouri, which has reported nearly 200 cases of
mumps infection this academic year [2016-17], has asked students to
refrain from throwing social engagements on campus and asked students
to avoid public places like bars in order to stem the outbreak.

Harvard University [Massachusetts] and the State University of New
York have each reported more than 60 confirmed mumps cases since last
spring [2016], joining dozens of other campuses facing control issues
with the disease commonly caused by exposure to sneezing, coughing or
sharing cups and utensils.

For many colleges and universities, the greatest challenge is not in
identifying or treating outbreaks among students but in trying to
force students to change their social habits so that infection can be
properly contained.

>From a public relations perspective, colleges which deliver
information about the infection and quarantine instructions are best
prepared for questions from parents, students and the media, and are
the most likely to avoid suffering negative reactions in enrollment or
coverage according to how transparent they can be about causes and
responses to illness outbreaks.

[Risk of infection with mumps (and measles) in colleges is high
because of waning immunity following childhood vaccination with MMR
and close associations among students in such settings. See recent
mumps posts for discussion of waning immunity, especially against
mumps, following MMR vaccine. While a 3rd vaccine prior to entering
college may help control outbreaks, it may not be cost-effective. An
alternative approach is to educate students about preventive practices
and isolation to control virus transmission once an infected student
is identified. - Mod.LK
