This timing is crucial because children are at an increased risk for contracting these diseases at this age, and administration of the MMR vaccine helps to ensure they develop immunity before they are exposed to the viruses.

The MMR vaccine is essential because measles, mumps, and rubella can cause serious health complications in young children. For example, measles can lead to pneumonia and encephalitis, mumps can cause orchitis and meningitis, and rubella is particularly dangerous during pregnancy due to the risk of congenital rubella syndrome.

Other vaccines mentioned, such as hepatitis B, are usually administered earlier in infancy, specifically within the first few months of life and again at 6-18 months. Diphtheria vaccination is part of the DTaP series, which starts at 2 months and continues through a series of doses given during the first few years of life, with a booster in early school age. Inactivated polio virus (IPV) vaccination also follows a similar schedule, starting at 2 months and continuing as part of the early childhood immun
