Elovac-B Injection (Hepatitis B Vaccine) – Prevention of Hepatitis B Virus Infection

Elovac-B Injection is an active immunizing agent used to prevent hepatitis B virus (HBV) infection in individuals at risk of exposure. This vaccine is essential for infants, children, and high-risk adults, including healthcare workers, sexually active individuals, and those with chronic liver conditions. Administered by healthcare professionals, It stimulates the immune system to produce protective antibodies against HBV, offering long-term protection. The vaccine is safe, effective, and recommended as part of routine immunization schedules worldwide. It cannot cure existing hepatitis B infections but is highly effective in preventing new infections when administered as per the prescribed dosage schedule.

Uses of Elovac-B Injection:

– Prevention of Hepatitis B virus infection
– Protection against liver cirrhosis and cancer caused by HBV
– Recommended for newborns, children, and high-risk adults

Benefits of Elovac-B Injection:

– Prevents HBV transmission through blood, saliva, or sexual contact
– Reduces risk of chronic liver disease, including cirrhosis and liver cancer
– Safe for all age groups, including infants and pregnant women (under medical supervision)
– Long-lasting immunity with complete vaccination course

Side Effects of Elovac-B Injection:

Most side effects are mild and temporary:
– Injection site reactions (redness, swelling, pain)
– Low-grade fever
– Fatigue
– Decreased appetite

These typically resolve within 1–2 days. Consult a doctor if symptoms persist.

How to Use Elovac-B Injection?

– Administered by a doctor/nurse only (intramuscular injection).
– Standard schedule: 3 doses at 0, 1, and 6 months.
– Infants: First dose at birth, followed by additional doses as per pediatrician’s advice.
– Do not self-administer.

How Elovac-B Injection Works?

It contains inactivated hepatitis B surface antigen (HBsAg). When injected, it triggers an immune response, prompting the body to produce antibodies against HBV. This “mild infection” simulation does not cause illness but prepares the immune system to fight actual HBV exposure effectively.

Safety Advice

– Alcohol: Consult a doctor (no known interaction).
– Pregnancy: Generally safe; consult your doctor.
– Breastfeeding: Safe; limited risk to infants.
– Driving: No impact on alertness.
– Kidney/Liver Disease: Safe; no dose adjustment needed.

Q1. Who should get vaccinated with Elovac-B Injection?

All newborns, children up to 19 years, healthcare workers, sexually active adults, and individuals with chronic liver disease/HIV should receive this vaccine.

No. While symptoms may resolve in 4–8 weeks, the virus can remain dormant in the body for life, potentially causing chronic liver damage.

Q3. Can hepatitis B be fatal?

Yes. Chronic HBV infection may lead to liver cirrhosis, cancer, or liver failure, which can be life-threatening.

Q4. How does hepatitis B spread?

HBV spreads through contact with infected body fluids (blood, saliva, semen) or shared needles/razors. It can also transmit from mother to baby during childbirth.

Q5. Does Elovac-B cause fever?
