What is Hepatitis B?
Hepatitis B is a viral infection that attacks the liver, caused by the Hepatitis B virus (HBV).While often associated with sexual transmission, it can spread through various routes, making early vaccination a critical preventative measure. The hepatitis B vaccine is a cornerstone of preventative healthcare, especially for newborns.
The virus is transmitted through contact with infected body fluids – blood, semen, and vaginal secretions. Transmission can occur through sexual contact,sharing needles during drug use,and from mother to child during birth. Hepatitis B, sometimes called hep B, can lead to chronic liver disease, cirrhosis, liver cancer, and even death.
why Vaccinate Newborns?
Experts overwhelmingly agree that vaccinating newborns against hepatitis B is a vital public health intervention. The primary reason is the high risk of chronic infection when HBV is contracted early in life. Approximately 90% of infants infected with HBV at birth develop chronic infection, compared to only 5-10% of adults. chronic infection considerably increases the risk of long-term health complications.
Most infants acquire hepatitis B from their mothers during delivery. While screening pregnant women for HBV is standard practise, access to prenatal care isn’t universal, and some infections may go undetected. Vaccination provides immediate protection,nonetheless of the mother’s infection status.
The Vaccination Schedule
The hepatitis B vaccine is typically given in a series of three doses:
| Dose | Timing | Administration |
|---|---|---|
| Dose 1 | Within 24 hours of birth | Intramuscular injection |
| Dose 2 | 1-2 months of age | Intramuscular injection |
| Dose 3 | 6-18 months of age | Intramuscular injection |
This schedule ensures robust and long-lasting immunity. The Centers for disease Control and Prevention (CDC) provides detailed data on the vaccination schedule.
