Bharat Biotech: Achieving a Milestone in Vaccine Development with Typbar TCV®
Immunisation for all is humanly possible. Global partnerships, such as Gavi and WHO’s Immunization Agenda 2030, demonstrate that when nations unite, even the most vulnerable populations can be vaccinated. By addressing global health challenges with affordable, high-quality vaccines, Bharat Biotech continues to strengthen public health infrastructure worldwide. Typbar TCV® is a testament to its innovation, saving lives and setting new benchmarks in vaccine development.
Bharat Biotech, a pioneering Indian biotechnology company, has significantly advanced global health with its innovative vaccines. One of its standout achievements is Typbar TCV®, the world’s first Typhoid Conjugate Vaccine (TCV), prequalified by the World Health Organization (WHO). Evaluated in Human Challenge Studies at Oxford University, Typbar TCV® demonstrated 100% immunogenicity and prevents up to 87.1% of infections, based on real-life definitions. This Vaccine offers long-lasting immunity against typhoid fever, a life-threatening disease affecting millions, particularly children in developing nations. Unlike traditional vaccines, Typbar TCV® is effective in infants as young as six months and provides robust protection with a single dose, helping combat antimicrobial-resistant typhoid strains.
Bharat Biotech’s commitment to cutting-edge research extends beyond Typbar TCV®. The company played a crucial role during the COVID-19 pandemic by developing COVAXIN, India’s first indigenous vaccine and the world’s first Intranasal COVID-19 vaccine, iNCOVACC. With a portfolio spanning Polio, Rotavirus, Japanese Encephalitis, Rabies, Zika, Chikungunya, Cholera, and Malaria vaccines, Bharat Biotech exemplifies "Make in India" excellence in biotechnology.
Pfizer: Advancing Adult Immunization Through Innovation and Impact
With a legacy spanning over 170 years, Pfizer remains one of the world’s leading pharmaceutical companies, powered by science and innovation. In India, Pfizer Limited delivers expert therapies across four core business categories: Vaccines, Hospitals, Internal Medicine, and Inflammation & Immunology. As a pioneer in vaccine development, Pfizer has introduced groundbreaking solutions such as Comirnaty® (COVID-19 vaccine), Prevnar 13® (Pneumococcal vaccine), and Trumenba® (Meningococcal vaccine), reinforcing its commitment to addressing global health challenges through a research-driven approach.
Pfizer’s high-quality vaccines are designed to make a meaningful impact at every stage of life, helping protect as many individuals as possible from life-threatening diseases. Driven by a passion for science, a commitment to excellence, and a strong focus on public health, Pfizer continues to lead bold advancements in research, development, and world-class manufacturing. This passion shapes every breakthrough and defines the company's purpose.
In India, Pfizer has collaborated with several leading hospitals to establish Centres of Excellence (CoEs) dedicated to advancing patient care through comprehensive adult vaccination programs. These centers focus on protecting against various vaccine-preventable diseases, including Pneumococcal disease, Influenza, Human Papillomavirus (HPV), and Hepatitis A and B.
With nearly 95% of deaths from vaccine-preventable diseases occurring among adults in India, the importance of adult vaccination cannot be overstated. Despite strong scientific evidence supporting adult immunization to enhance quality of life, awareness and adoption rates remain low. Pfizer’s CoEs aim to bridge this gap by empowering healthcare professionals with the knowledge and tools needed to advocate for timely adult immunization, particularly for individuals with chronic conditions such as COPD, asthma, diabetes, heart or kidney disease, and other immunocompromising conditions. Individuals with risk factors such as smoking, exposure to high pollution levels, or those aged 50 and above, are also encouraged to consult healthcare providers about vaccination as an essential preventive health measure.
Every day, Pfizer remains committed to creating a healthier world by inventing, developing, and championing vaccines that offer vital health benefits across all stages of life.
