Did You Know? Hepatitis B Is Preventable Through Vaccination

Hepatitis B is a serious liver infection caused by the hepatitis B virus (HBV), affecting millions of people worldwide. Despite its prevalence and potential complications—including chronic liver disease, cirrhosis, and even liver cancer—the good news is: Hepatitis B is preventable. And the key to prevention? Vaccination.

Why Is Hepatitis B a Concern?

Hepatitis B can be transmitted through contact with infected blood or bodily fluids, often through unprotected sex, sharing of needles, or from mother to child during childbirth. In many cases, the infection can become chronic—especially in infants and young children—and silently damage the liver over time without showing symptoms.

In Singapore, Hepatitis B is a significant public health concern. Fortunately, the inclusion of the Hepatitis B vaccine in the National Childhood Immunisation Schedule (NCIS) has dramatically reduced transmission rates in recent years.

How the Hepatitis B Vaccine Protects You

The Hepatitis B vaccine is safe, effective, and readily available. It works by stimulating the immune system to produce antibodies against HBV, offering long-term protection. The full vaccination schedule usually includes three doses over six months, although newer combination vaccines may reduce the number of injections required.

Once vaccinated, most people develop immunity for life, making this one of the most effective tools in preventing hepatitis B and its associated complications.

Who Should Get Vaccinated?

Vaccination is recommended for:

• Newborns and infants (as part of national immunisation programmes)
• Healthcare workers and caregivers
• People with multiple sexual partners
• Those with chronic liver or kidney disease
• Household contacts or sexual partners of infected individuals
• Travellers to regions with high HBV prevalence

If you're unsure of your status, a simple blood test can determine whether you are immune, infected, or still susceptible to the virus.

Stay informed. Stay empowered. And most importantly — stay ahead.

Hepatitis B may be silent, but vaccination speaks volumes. If you or your loved ones have not been vaccinated, speak to a healthcare professional today. A small step can make a life-saving difference.
