In the landscape of immunology, the Adsorbed Diphtheria Tetanus (DT) vaccine stands as a cornerstone of the Expanded Program on Immunization (EPI). As a premier supplier, Jiangxi Serum Pharma Industries Co., Ltd. recognizes that the "adsorption" process—typically using aluminum hydroxide or aluminum phosphate—is not just a chemical addition but a sophisticated bio-engineering feat designed to enhance the immunogenicity of the toxoids.
Adsorption creates a "depot effect," allowing for the slow release of the antigen at the injection site. This prolonged exposure stimulates a robust B-cell and T-cell response, ensuring long-term memory cells against Corynebacterium diphtheriae and Clostridium tetani.
Our DT vaccines utilize ultra-purified toxoids, achieving a purity level that exceeds WHO standards. We focus on minimizing residual formaldehyde and other process impurities to reduce adverse local reactions while maintaining maximum potency.
Clinical data across diverse populations confirms that adsorbed vaccines provide significantly higher antitoxin titers compared to fluid vaccines, particularly in pediatric and geriatric demographics where immune response may be naturally suppressed.
Jiangxi Serum Pharma Industries Co., Ltd. is a professional supplier of pharmaceutical and nutritional products in China. For nearly 10 years, we have been dedicated to exporting biological products, vaccines, Western medicines, raw materials, intermediates, medical consumables, food additives, and plant extracts, and have accumulated rich industry experience.
Our pharmaceutical products consist of biological products, vaccines, western medicines, raw material, intermediates, medical consumables, with high quality and affordable prices.

The global pharmaceutical market demands more than just manufacturing; it demands supply chain integrity. Jiangxi Serum Pharma leverages China’s advanced industrial cluster to provide unparalleled efficiency in vaccine distribution.
From the raw fermentation of bacteria to the automated filling of vials, the Chinese pharmaceutical ecosystem provides a cost-to-potency ratio that is unmatched globally. Our facilities utilize AI-driven logistics to ensure no bottlenecks in the distribution of temperature-sensitive DT vaccines.
We implement "Smart Cold Chain" monitoring. Every batch of Adsorbed Diphtheria Tetanus Vaccine is tracked with IoT sensors that log temperature data in real-time, ensuring the cold chain (2°C to 8°C) is never breached during transit to Southeast Asia, Africa, or Latin America.
Our production lines are certified by NMPA (China) and aligned with WHO-GMP guidelines. This ensures that every dose delivered meets the stringent E-E-A-T requirements of health ministries worldwide.
We are exploring co-crystallization techniques to stabilize toxoids at room temperature, potentially reducing the dependence on cold-chain infrastructure in remote areas.
Advanced high-density bio-fermentation allows for higher yields of purified diphtheria and tetanus toxins, ensuring we can meet the surge in demand during global health emergencies.
Research into TLR4 agonists alongside traditional aluminum salts aims to create "dose-sparing" vaccines that provide immunity with smaller antigen quantities.
The Adsorbed Diphtheria Tetanus Vaccine is not a one-size-fits-all product. Its application varies based on regional epidemiological needs:
Currently, the global DT vaccine market is seeing a shift towards Multivalent Combinations. However, the standalone Adsorbed DT vaccine remains vital for adult booster doses and specific pediatric contraindications to Pertussis components. Jiangxi Serum Pharma remains at the forefront of this niche, providing stability where others pivot.
Our DT vaccines typically have a shelf life of 24 to 36 months when stored at the recommended temperature of 2°C to 8°C. Do not freeze, as freezing destroys the adsorption structure of the aluminum adjuvant.
Yes, while primarily used in children under 7 who cannot receive the Pertussis component, our DT vaccine is also utilized in adult formulations (often as Td) for decennial boosters or wound management.
Every batch undergoes rigorous Lf (Limit of Flocculation) testing and in-vivo potency assays to ensure that the antigenic content is consistent with the labeling and regulatory approvals.
We provide full CTD (Common Technical Document) dossiers, stability data, and GMP certificates to assist our partners in local MOH registrations across over 50 countries.
Serum Pharma will continuously monitor the development of the cutting-edge markets. Currently, we have already cooperated with our partners on the customization of Pre-Mix, Co-Crystallization and Bio-Fermentation products service.
