India-based Shantha Biotechnics is progressing with its plans to introduce DTP+ Hep B+ Hib pentavalent vaccine -- which protects against diphtheria-tetanus-pertussis, hepatitis B and haemophilus influenza type B -- by the end of 2006.
The company is also in the process of developing a series of other new vaccines, it added.
The market size for the combination vaccine in India is estimated at $50 million. Distributed though UNICEF, the vaccine is likely to reach approximately 60 countries by the end of this year.
