AIM Honesty Biopharmaceutical Co., Ltd., a trusted Chinese vaccine factory under the listed AIM Vaccine Group, independently develops and produces high-performance Hepatitis B Vaccine Hansenula Polymorpha. Built on the world-class Hansenula Polymorpha expression platform and patented adjuvant technology, this human immunization vaccine delivers stable, superior immune response, exceeding conventional yeast and cell-based hepatitis B vaccine products. With over 20 years of market validation and nearly 500 million cumulative doses used nationwide, it serves as a core preventive solution for HBV infection control for newborns, medical staff and high-risk groups worldwide.
This advanced yeast-derived immunization product is formally branded as RECVAX®, professionally manufactured and exported by AIM Honesty Biopharmaceutical Co., Ltd. Different from traditional Saccharomyces cerevisiae and CHO cell vaccine routes, Hepatitis B Vaccine Hansenula Polymorpha adopts a cutting-edge recombinant yeast expression system with zero antibiotic and zero bovine serum albumin addition throughout production. It effectively avoids exogenous contamination risks and achieves industry-leading purity and safety standards, making it a preferred long-term immune protection vaccine for global public health procurement.
As a key commercial product of AIM Vaccine Group, this vaccine benefits from the group’s five validated vaccine technology platforms and strict GMP standardized production systems. It maintains consistent batch stability and excellent clinical performance, supporting large-scale bulk export and cross-border medical project cooperation.
Hepatitis B virus infection is one of the leading causes of chronic liver diseases, cirrhosis and primary liver cancer globally. Statistical data shows that chronic HBV infection affects over 296 million people worldwide, causing approximately 820,000 annual deaths from liver failure and malignant liver lesions. Effective vaccination remains the most economical and reliable public health intervention to block viral transmission and reduce long-term liver disease risks.
Hepatitis B Vaccine Hansenula Polymorpha is designed specifically for HBV infection prevention. It induces the human body to produce targeted hepatitis B surface antibodies, establishing a stable immune barrier against viral invasion. Standard immunization can effectively block mother-to-child transmission, occupational exposure infection and daily contact transmission, significantly reducing the incidence of chronic hepatitis B and subsequent liver cancer risks.
This optimized recombinant hepatitis B immunization vaccine is suitable for all HBV-susceptible populations, covering pediatric and adult groups with differentiated protection demands. It provides targeted immune defense for high-risk groups with frequent exposure risks.
1. Newborn infants, especially babies delivered by HBsAg and HBeAg double-positive mothers, effectively blocking vertical mother-to-child HBV transmission.
2. Clinical healthcare workers, laboratory researchers and medical staff who are regularly exposed to human blood and bodily fluid samples with high viral exposure probability.
3. Adults living in high-incidence areas, personnel engaged in high-risk public health positions, and individuals requiring long-term regular immune protection against hepatitis B virus.
AIM Honesty Biopharmaceutical implements stricter internal pharmacopoeia standards than industrial norms for Hepatitis B Vaccine Hansenula Polymorpha.

Different from conventional hepatitis B vaccines, Hepatitis B Vaccine Hansenula Polymorpha adopts exclusive patented adjuvant and in-situ adsorption technology. After inoculation, it forms a stable antigen bank inside the human body, realizing sustained and slow antigen release. This mechanism prolongs immune stimulation duration and significantly enhances overall immune response, bringing more durable and reliable protective effects.
Clinical academic research led by academician institutions has verified its outstanding performance. In comparative booster immunization trials covering children aged 5 to 15, the 10μg Hansenula Polymorpha yeast vaccine achieved an 83.4% anti-HBs seropositive rate within eight years after booster vaccination, ranking the highest among four mainstream vaccine groups. Its long-term immune persistence far exceeds traditional products.
With two decades of stable market promotion, the RECVAX® vaccine series has covered all 31 provincial-level administrative regions in China, serving nearly 80% of domestic newborn immunization programs. The cumulative clinical dosage has reached nearly 500 million doses, proving stable and safe mass application capacity.
