New Delhi: As many as eight vaccine candidates for Covid-19 are under different stages of clinical trials which could be ready for authorisation in near future, the ministry of health(vaccines) and family welfare informed.
The union health ministry informed that the eight vaccines include Astrazeneca and Oxford university developed and Serum Institute of India manufactured Covishield, Covaxin by Bharat Biotech Limited, ZyCoV-D by Zydus Cadila, Russian vaccine candidate Sputnik-V, NVX-CoV2373 by SII, HGCO19 by Geneva, and two unlabeled vaccines — Recombinant Protein Antigen based vaccine by Biological E Limited — and Inactivated rabies vector platform by Bharat Biotech.
While the former five vaccine candidates have entered either phase II or phase III clinical trials, the latter three are in pre-clinical trial phases, the ministry informed. Union health secretary Rajesh Bhushan said that few of the vaccine candidates may receive license for authorisation in next few weeks.
“The complete immunization in all the eight candidates would require 2-3 doses of it inoculated at the gap of 3 to 4 weeks,” he added. He also cautioned that COVID precautions must be undertaken even after the vaccination.
The UK on Wednesday became the first country to approve the Pfizer/BioNTech vaccine against COVID-19, with the UK regulator Medicines and Healthcare products Regulatory Agency granted approval to Pfizer’s vaccine for EUA on Wednesday last week.
Pfizer’s vaccine would require -70 degree celsius of temperature for its storage. Experts have raised doubts that the extreme low temperature required for storing the vaccine poses a big challenge for its delivery in a country like India, especially in its smaller towns and rural areas where maintaining such cold chain facilities would be very difficult.
