Hepatitis B is a serious liver infection caused by the hepatitis B virus (HBV). It can lead to chronic liver disease, cirrhosis, liver cancer, and even death. Vaccination is the most effective way to prevent hepatitis B. This article explores the details of the hepatitis B vaccine, its importance, how it works, and answers frequently asked questions.
What is the Hepatitis B Vaccine?
Overview of the Hepatitis B Vaccine
The hepatitis B vaccine is a safe and effective immunization that protects individuals from HBV infection. It contains a purified protein from the hepatitis B virus, which triggers the immune system to produce antibodies without causing infection.
Types of Hepatitis B Vaccines
- Single-Antigen Vaccines: Protect against hepatitis B only (e.g., Engerix-B, Recombivax HB).
- Combination Vaccines: Protect against hepatitis B and other diseases, such as DTaP-HepB-IPV (Pediarix).
Importance of Hepatitis B Vaccination
- Preventing Chronic Liver Disease
Hepatitis B infection can become chronic, leading to severe liver damage, cirrhosis, and liver cancer. Vaccination prevents such long-term complications.
- Reducing Transmission
HBV is highly infectious and can spread through blood, sexual contact, and from mother to child during childbirth. Vaccination breaks the chain of transmission.
- Public Health Impact
Mass vaccination programs have drastically reduced hepatitis B infections worldwide, especially in regions with high HBV prevalence.
Who Should Get the Hepatitis B Vaccine?
Universal Recommendations
- Infants: All newborns should receive their first dose within 24 hours of birth.
- Children and Adolescents: Unvaccinated individuals up to age 18 should complete the vaccine series.
High-Risk Groups
- Healthcare workers exposed to blood or body fluids.
- Individuals with chronic liver disease or hepatitis C.
- Travelers to regions with high hepatitis B prevalence.
- People who inject drugs or engage in high-risk sexual behavior.
- Household contacts of HBV-infected individuals.
Adults
Vaccination is recommended for all unvaccinated adults, especially those at higher risk of infection.
Vaccination Schedule and Dosage
