The mumps virus was first identified as the cause of mumps in 1934 and was first isolated in 1945. Within a few years after isolation, vaccines protecting against MuV infection had been developed. MuV was first recognized as a species in 1971, and it has been given the scientific name Mumps orthorubulavirus.

Elderly rodents typically die of cancer or kidney disease, but not of cardiovascular disease. In humans, the relative incidence of cancer increases exponentially with age for most cancers, but levels off or may even decline by age 60–75 [3] (although colon/rectal cancer continues to increase). [4]
Mumps vaccines are vaccines which prevent mumps. [1] When given to a majority of the population they decrease complications at the population level. [ 1 ] Effectiveness when 90% of a population is vaccinated is estimated at 85%. [ 2 ]
In today's world individuals are living longer. According to the United Nations World Populations Prospect (2020), [38] the average life expectancy is 78.93 years which is a 0.16% increase since 2018. With the elderly population becoming more popular, there is a crucial need for gerontological nursing research.
Immunosenescence involves both the host's capacity to respond to infections and the development of long-term immune memory. Age-associated immune deficiency is found in both long- and short-lived species as a function of their age relative to life expectancy rather than elapsed time. [2]
The average life expectancy in Europe during the Middle Ages was 35 years; 60% of children died before the age of 16, many of them during their first 6 years of life. Physicians – what few there were – relied as much on astrology as they did on their limited medical knowledge.
