I am interested in this question. Because as i interpret most (>95%) acquire immunity either thru clinical infection or immunization. But have seen adults with measles?
So YES if we are sure the adult adult person is non-immune then why not?
evidence as its an important public health issue

Yes, for example, I was infected with measles when I was 22 years old

Generally children are vaccinated between 12-18 months. But if some missed the vaccine they should take it at the adolescent / adult age.
Yes an adult can be vaccinated
I think that adults who aren't immunised even if they are vaccinated need to be vaccinated. In Madagascar, there are epidemic of measles and there are many adults.
We are at the dawn of a new paradigm in measles epidemiology in countries which have achieved sustained interruption of measles circulation through vaccination. The long suspected phenomena of waning immunity in vaccinated individuals now appears to be a confirmed fact. These countries are now witnessing the resurgence of measles outbreaks, but this time among vaccinated individuals, mostly adults. For a long time these adults have not experienced the immunological boosters caused by repeated contacts with the virus, their immunity levels have waned and left them unprotected to infection. When diseased, vaccinated individuals present ‘vaccine-modified measles’, characterized by less severe symptoms which rarely fulfill the clinical definition of classical measles. The contagiousness of this atypical form of disease appears to be much more limited than classical measles.
Portugal is one such countries where measles has been eliminated for over a decade. A growing proportion of the adult population experienced the last contact with the virus (in its attenuated vaccine form) at around 6 years of age. A recent serological survey (2015-2016) showed that the percentage of seropositive individuals presents a clear depression between ages 15 and 29, with minimum values in the 20-29 years old range, where only 77.9% were seropositive. Nevertheless these same individuals had levels of protection above 95% when they were surveyed back in 2002. It thus appears that in the course of 13-14 years, the concentration of antibodies in 17-19% of these cohorts waned and fell below the critical threshold that warrants protection. During this period, there was no endogenous circulation of measles in Portugal.
This new paradigm needs to be dealt with and adult vaccination is one possibility.
Yes, adults who do not have acceptable presumptive evidence of immunity against measles (written documentation of vaccination, laboratory evidence of immunity or of confirmation of measles disease) and who do not have contraindications for Measles-Mumps -Rubella (MMR) vaccine should receive 2 doses of vaccine separated by at least 28 days. In the USA, persons born before 1957 are considered immune. Other countries have also set age limits.
