India moves closer to dengue vaccine as final trials underway

More than 10,000 volunteers participate in trials for DengiAll, which could provide affordable, long-term protection against all four dengue serotypes in a single dose.

  • This year, Panacea Biotec began final Phase III trials of DengiAll in India, with results expected later this year.
  • India has seen a surge in dengue cases and deaths since 2021, with over one million cases and at least 1,500 deaths; the WHO says rising temperatures and rainfall spread Aedes mosquitoes.
  • Inside Panacea's research labs, Dr Priyanka Priyadarsiny described development steps from proof-of-concept to regulatory checks, with the candidate based on a strain from the US National Institutes of Health and developed by Panacea as the most advanced of three Indian firms with its own formulation and patent.
  • In India, final approval would come from the Drug Controller General of India and WHO prequalification would be required for large-scale international use, with over 10,000 volunteers enrolled and rollout possible as early as next year if results are favorable.
  • Most existing dengue vaccines require multiple doses, making DengiAll's single-dose potential notable, as it could protect people aged one to 60 and address scientific challenges from all four serotypes.
