Mumps, medically known as parotitis, is a viral infection that leads to swelling of the salivary glands, typically located near the ear in the jaw area. While this condition is most common in children, adults can also contract it.

The Paramyxovirus virus is responsible for causing mumps, and it spreads through saliva droplets, coughing, or sneezing from an infected individual. One common question many people ask is whether it’s possible to get mumps again after having had it once.

Can Mumps Happen Again?

Generally, once a person has had mumps, the chances of contracting it again are very low. After an initial infection, the body produces antibodies that protect against future infections by recognizing and fighting the virus.

These antibodies typically provide lifelong immunity, meaning most individuals who recover from mumps are protected from reinfection. However, while reinfection is rare, it can still happen under certain conditions.

Reinfection may occur if the immune system is compromised or if a different strain (or version) of the virus is involved.

Some medical conditions, such as HIV or diabetes, can weaken the immune system, increasing the likelihood of reinfection. Additionally, individuals who have not received full immunization may be at higher risk.

The Role of the MMR Vaccine in Preventing Mumps

The MMR (Measles, Mumps, Rubella) vaccine plays a key role in preventing mumps. The vaccine is about 78% effective after the first dose and up to 88% effective after the second dose.

To achieve optimal protection, the MMR vaccine is given in two doses: the first dose is typically administered at 12-15 months, and the second dose is given at 4-6 years of age.

The MMR vaccine prevents mumps in the following ways:

• The MMR vaccine contains a weakened version of the virus, prompting the immune system to produce antibodies against mumps, as well as measles and rubella.
• Widespread vaccination helps reduce the virus's ability to spread. When a significant portion of the population is vaccinated, it’s harder for the virus to find a host.
• The MMR vaccine is especially effective as preventive measures in environments where people are in close contact, such as schools and colleges.
• Vaccination also helps prevent severe mumps complications, including inflammation of the testicles, ovaries, pancreas, and meningitis.

Although the MMR vaccine is not 100% effective, it remains the most effective way to protect yourself and others from mumps. It helps control the spread of the disease, preventing outbreaks and severe health issues.

If you have questions about mumps or the MMR vaccine, you can consult with a healthcare professional through the Ai Care app, available for download on the App Store or Play Store.
