Uptake of the measles, mumps and rubella vaccine is below the 95% target. Cases of mumps in England have reached a decade high, data shows. The viral infection is defined by painful swelling in the side of the face under the ears, leading to a "hamster" appearance. Most cases pass in a week or two with rest, fluids and painkillers. Around one in seven sufferers, however, develop viral meningitis.

This is the highest cases have reached since 7,662 incidences were reported across England and Wales in 2009. An outbreak occurred in 2005, resulting in 43,378 confirmed cases. This was put down to "gaps in eligibility" of the measles, mumps and rubella (MMR) jab. Last month, 546 cases were confirmed in England, compared to 191 in January 2019, the Independent reported. One Leeds University student reportedly needed morphine to cope with the pain, while another told the BBC her jaw "pretty much locked". Why is mumps on the rise? The rise in cases has been blamed on falling uptake of the MMR vaccine. The NHS offers the jab as part of its routine childhood immunisation schedule. One dose is given when a child is around 12-to-13 months, and a booster at three years and four months. Both doses are said to provide 95% protection against mumps. NHS Digital data shows 94.5% of five year olds in England had been immunised with the first MMR dose in 2018/19, down from 94.9% in 2017/18 - both below the 95% immunisation target. Even if not everyone has been vaccinated, having an immunisation rate of 95% can ward off an outbreak due to "herd immunity". Herd immunity means enough of the public have been vaccinated for an infection not to be able to "take hold". This protects those who may be unable to get vaccinated, like cancer or HIV patients.

Students struck with mumps likely missed out on the vaccine when they were children. This may have coincided with the now discredited "research" from the then-gastroenterologist Andrew Wakefield, who mistakenly linked the MMR jab to autism. This has repeatedly been dismissed, with Wakefield struck off. The MMR vaccine is also said to be less effective at protecting against mumps than measles or rubella. Nonetheless, four out of five people caught mumps before the jab was introduced in the UK in 1988, mainly school children. Officials are urging those who missed out to get up-to-date on their vaccines. "It is of concern we are seeing large numbers of cases of mumps," said Professor Helen Bedford from University College London. "These are mainly occurring among older teens and young adults who either had no doses of MMR vaccine when they were young or only had one dose. "However, we also know the immunity from mumps vaccine can wane over time. This means you can still get mumps even if fully vaccinated. "Although mumps can be nasty especially in people past puberty, it is usually much milder in previously-vaccinated people, so the best way to avoid mumps is to get the vaccine. "If you haven't been vaccinated, it's never too late to have the MMR vaccine." Mumps causes painful swelling on the side of the face below the ears. What is mumps? As well as the tell-tale swollen face, mumps can trigger headache, joint pain and fever. Many confuse these symptoms for glandular fever or tonsillitis. The virus spreads like a cold or flu, via infected droplets of saliva inhaled by the nose or mouth.
