BMI has developed proprietary technology that overcomes immunological, technical, and safety issues associated with the current vaccines, while also enabling a more rapid and lower cost manufacturing process.
ultra-IPV is produced using proprietary inactivation technology. Viruses are complexed with a manganese-decapeptide-phosphate (MDP) mixture and then exposed to UV light. A very quick, easy and reproducible process. The MDP system has been adapted from radiation-resistant bacteria such as Deinococcus radiodurans.
The use of attenuated Sabin strains to produce the vaccine greatly reduces safety and biosecurity concerns. This non-chemical inactivation process uses ultraviolet light resulting in reduced damage to the immunogenic surface features of the virus.
BMI's process is rapid (less than a minute compared with 2-4 weeks for formalin-inactivation) and requires less downstream processing than IPV.
ultra-IPV vaccine stimulates high titers of virus-neutralizing antibodies in animal models.
Mass spectrometric analysis of ultra-IPV and two commercially available IPV products indicate that many more doses of ultra-IPV can be made than IPV per starting quantity of virus.
ultra-IPV is expected to have a similar safety profile as IPV in vaccines with the exception that the use of formaldehyde is avoided.
