What immunization is administered at birth?

The immunization administered at birth is the Hepatitis B vaccine. This vaccine is important because it protects infants from the Hepatitis B virus, which can lead to serious liver infections and chronic liver disease later in life. Administering this vaccine at birth helps ensure early protection, especially for infants who may be at higher risk of exposure, such as those born to mothers with Hepatitis B or when the mother’s status is unknown.

In contrast, the other vaccines mentioned are scheduled for administration at different ages. Varicella, which protects against chickenpox, is typically given when the child is around 12 to 15 months old. The DTP (Diphtheria, Tetanus, and Pertussis) vaccine is administered in a series starting at 2 months of age. The MMR vaccine, which protects against measles, mumps, and rubella, is usually given between 12 and 15 months of age. Therefore, Hepatitis B stands out as the only vaccine given at birth, making it crucial for early immunity against Hepatitis B.
