Overview
The MMR vaccine is a combined immunization that protects against Measles, Mumps, and Rubella, three highly contagious viral infections. It is recommended as a routine childhood vaccine and for certain adults who are not immune.
In Korea, the MMR vaccine is widely available at public health centers, pediatric clinics, and hospitals, ensuring high vaccination coverage and effective prevention of outbreaks.
Highlights:
- ✅ Protects against measles, mumps, and rubella
- ✅ Reduces risk of serious complications
- ✅ Safe and widely used in children and adults
- ✅ Can be part of routine immunization schedules
What is the MMR Vaccine?
The MMR vaccine is a live attenuated vaccine that stimulates the immune system to produce antibodies against the three viruses:
- Measles: Highly contagious virus causing fever, rash, and complications like pneumonia or encephalitis
- Mumps: Causes swelling of salivary glands, fever, and rare complications such as meningitis or infertility
- Rubella: Mild illness in children but can cause severe birth defects if contracted during pregnancy
Important: The vaccine is preventive, not therapeutic, meaning it protects before exposure to the viruses.
What are the benefits?
- Disease prevention: Strong immunity against measles, mumps, and rubella
- Reduced outbreak risk: Protects communities by creating herd immunity
- Safe for most individuals: Mild side effects are rare and usually short-lived
- Protection during pregnancy: Immunity before pregnancy prevents rubella-related birth defects
Key benefits highlighted:
- ⚡ Long-lasting immunity after two doses
- ⚡ Significant reduction in hospitalizations and complications
- ⚡ Contributes to public health by preventing epidemics
- ⚡ Widely recommended by WHO and national health authorities
Procedure Details
1) How should I prepare for the MMR Vaccine?
- Medical history: Inform your healthcare provider of allergies, pregnancy, or immunodeficiency
