That compares with the 95% efficacy of the two-shot vaccine from Pfizer/BioNTech, the other vaccine approved in Britain. A separate mRNA vaccine from Moderna, approved in the United States, costs up to $37. The AstraZeneca shot does not require deep freezing at minus 70 degrees like the mRNA vaccine from Pfizer and its German partner, BioNTech , and has already been produced by the millions of doses. Moderna's similar mRNA vaccine has also received US approval. India's drug regulator is also discussing emergency approval of the AstraZeneca vaccine, being made in partnership with the Serum Institute of India.
