Mother-to-child transmission is a major route of hepatitis B infection worldwide. When a mother carries the virus, her newborn can be infected during delivery — and infants infected at birth have a very high risk of developing chronic hepatitis B, which can lead to liver disease decades later. Birth-dose vaccination, ideally within 24 hours of delivery, is one of the most effective public health interventions available. It's also a key driver of demand in the hepatitis vaccine market.

The hepatitis vaccine market is shaped significantly by birth-dose programs and routine infant immunization schedules. Countries that have achieved high birth-dose coverage have seen dramatic declines in chronic hepatitis B among children and young adults.

Why Timing Matters

The earlier a newborn receives the vaccine, the more effective it is at preventing infection from perinatal exposure. Birth-dose vaccination, combined with other interventions like antiviral therapy for mothers with high viral loads, can reduce transmission to very low levels.

Program Implementation Challenges

• Cold chain requirements: vaccines must be stored and transported properly

• Delivery at birth: ensuring vaccination happens in all birth settings

• Follow-up doses: completing the full series is essential for long-term protection

• Awareness: educating families and birth attendants about the importance of timely vaccination

People Also Ask

When should the hepatitis B vaccine be given to newborns?
Ideally within 24 hours of birth, followed by additional doses according to the immunization schedule. Timely birth-dose vaccination is critical for preventing mother-to-child transmission.

Can hepatitis B be prevented in babies born to infected mothers?
Yes. Birth-dose vaccination, sometimes combined with hepatitis B immunoglobulin and antiviral treatment for the mother, can dramatically reduce transmission risk.

The Global Impact

Birth-dose vaccination has already changed the trajectory of hepatitis B in many countries. Continued investment in immunization infrastructure, cold chain systems, and maternal screening will be essential to reaching elimination targets — and will sustain demand for hepatitis vaccines in the years ahead.
