  • The infection has also been linked to cases of microcephaly, in which babies are born with underdeveloped brains.

  • Hyderabad-based Bharat Biotech has filed for global patent of two vaccine candidates – a recombinant vaccine and an inactivated vaccine – for Zika virus. The company announced that it could make available the inactivated vaccine in two years if the Indian Government fast-tracked the regulatory approvals once the pre-clinical trials proved to be successful. While the recombinant vaccine might take time, the pre-clinical testing of the inactivated vaccine in animals would be completed in five months.
