The salivary glands swell due to illness caused by mumps. This disease had become a plague in the 18th and 19th centuries. A Greek physician and philosopher named Hippocrates had first described about mumps in the 5th century BC. He gave the description about the symptoms, which include face and throat swelling, and in men testicles also swell.
This epidemic was quite widespread in the 18th century and 19th century. This epidemic broke all round the world, including in military barracks, prisons, boarding schools and ships at the sea. During the World War 1, French troops were attacked by mumps. Dr Johnson and Dr Good pasture were the ones who came out with a proof that a virus caused mumps in the year 1934.
Mumps vaccines are of three kinds which were invented in the 20th century. The three kinds are rubini, urbane and jeryl-lynn. At present the jeryl-lynn is used in the United States. This jeryl-lynn vaccine was invented in the 1960s, and it got approved by the US FDA in the year 1967.
The combination vaccine is also known as measles-mumps-rubella (MMR) was invented in the year 1971, and came into use in public in the year 1977. American schools made MMR vaccine compulsory in the 1990s.
Many concerns relating to the effectiveness of the mumps vaccine were raised in the recent past. In the year 2006, mumps outbreak in California caused many people, who were previously vaccinated, to fall ill. Also, physicians in England agreed that this vaccine may not be as effective as though earlier. This disease had become an epidemic in 1990s in north England and Northern Ireland.
