The Cambridge-based company did not give details on when it will start producing the vaccine for COVID-19, the disease caused by the new coronavirus, which has so far infected over 3 million people and killed more than 215,000. While there are more than 70 vaccines in development for the coronavirus, industry experts say they expect development of a successful vaccine to take at least 12-18 months, compared with the average vaccine development time of 5-7 years. The Jenner Institute and Oxford Vaccine Group have been working on a vaccine, called ChAdOx1 nCoV-19, and said earlier this month large-scale production capacity was being put in place to make millions of doses even before trials show whether it is effective.
